6:27 PM: John Beck(Ins): Is that fair?
6:27 PM: Brandis Lee: or is this for chapter 3

6:32 PM: Anna Oster: thank you
6:32 PM: Jamie Baldwin: hello how is everyone
6:32 PM: Jamie Baldwin: everyone^

6:34 PM: Sammy Ibrahim has entered the room.
6:34 PM: Crystal Peddicord: hi prof
6:34 PM: John Beck(Ins): Boy, what was that?
6:34 PM: Jamie Baldwin: lol
6:34 PM: John Beck(Ins): Hi, Sammy!
6:35 PM: Sammy Ibrahim: hello
6:35 PM: John Beck(Ins): Let's get started. Let me know when you are on Ch 3_p1, please.
6:35 PM: Jamie Baldwin: there
6:35 PM: Lindsay Gardner: I'm there
6:35 PM: Tynese Harris: got it
6:35 PM: Brandis Lee: on the walkthrough right
6:36 PM: John Beck(Ins): right, Brandis.
6:36 PM: Crystal Peddicord: im there
6:36 PM: Brandis Lee: ok im there
6:36 PM: John Beck(Ins): Okay, let's go to page 2, please.
6:36 PM: John Beck(Ins): we could just list all of the possible outcomes.
6:37 PM: John Beck(Ins): Or.... go to page 3, please.
6:37 PM: John Beck(Ins): Go to page 4, please.
6:37 PM: Shante Jackson has entered the room.
6:37 PM: John Beck(Ins): If you've ever watched the pic-three on TV, you've seen the 3 urns with 10 balls in each urn.
6:37 PM: John Beck(Ins): Hi, Shante.
6:38 PM: John Beck(Ins): Shante, we're on Ch 3_p4.
6:38 PM: John Beck(Ins): Go to page 5, please.
6:38 PM: Shante Jackson: thanks
6:38 PM: John Beck(Ins): There are 10 balls in the first urn, so there are 10 possible outcomes when we select the first ball.
6:38 PM: John Beck(Ins): Go to page 6, please.
6:39 PM: John Beck(Ins): The second urn also has 10 balls, so there are 10 possible outcomes when we select a ball from the second urn.
6:39 PM: John Beck(Ins): Go to page 7, please.
6:40 PM: Justin Ambrose has entered the room.
6:40 PM: John Beck(Ins): There are 10 balls in the 3rd urn, so there are 10 possible outcomes when we select a ball from the 3rd urn.
6:40 PM: John Beck(Ins): Hi, Justin!
6:40 PM: Justin Ambrose: hello
6:40 PM: John Beck(Ins): Justin, we are on Ch 3_p7.
6:40 PM: Justin Ambrose: ok
6:40 PM: John Beck(Ins): Go to page 8, pleases.
6:41 PM: John Beck(Ins): Thus there are 1000 possible outcomes when we select the "pick three."
6:41 PM: John Beck(Ins): Make sense?
6:41 PM: Lindsay Gardner: yes
6:41 PM: Jamie Baldwin: yes
6:41 PM: Tynese Harris: yes
6:41 PM: Anna Oster: yes
6:41 PM: Justin Ambrose: yup
6:42 PM: Crystal Peddicord: yes
6:42 PM: John Beck(Ins): Go to page 9, please.
6:43 PM: John Beck(Ins): Yes, if we knew which computers had problems we'd fix them before we ship them--- I think.
6:43 PM: John Beck(Ins): Go to page 10, please.
6:44 PM: John Beck(Ins): n1 is the number of ways we could ship 2 computers with video card problems.
6:44 PM: John Beck(Ins): n2 is the number of ways we'd ship 2 computers with hard drive problems.
6:44 PM: John Beck(Ins): etc.
6:44 PM: John Beck(Ins): Go to page 11, please.
6:45 PM: John Beck(Ins): we don't know which computers would have video card problems, but we do know that there are 3 with this problem and we are going to ship 2 of them
6:45 PM: John Beck(Ins): Make sense?
6:45 PM: Brandis Lee: so were doing combinations because the order doesn’t matter in this case
6:45 PM: Jamie Baldwin: yes
6:45 PM: Crystal Peddicord: yes
6:46 PM: John Beck(Ins): That's right, Brandis.
6:46 PM: Tynese Harris: ok
6:46 PM: Lindsay Gardner: ok
6:46 PM: Brandis Lee: ok
6:46 PM: John Beck(Ins): Go to page 12, please.
6:47 PM: John Beck(Ins): In our inventory there are 4 that have hard drive problems and we want to ship 2 of them. Hence C(4,2)
6:47 PM: John Beck(Ins): Okay?
6:47 PM: Brandis Lee: so if we work out these problems using the combination method thats why we get the answer 6
6:47 PM: John Beck(Ins): Yes, Brandis.
6:47 PM: Crystal Peddicord: ok
6:47 PM: Brandis Lee: ok
6:47 PM: Tynese Harris: got that
6:47 PM: Anna Oster: ok
6:47 PM: John Beck(Ins): Go to page 13,please.
6:48 PM: Theodora Soriano has entered the room.
6:49 PM: John Beck(Ins): we started with 20 computers. 3 had video card problems. 4 had hard drive problems. thus out of the 20 computers we have 13 that don't have problems.
6:49 PM: Brandis Lee: but I thought we were only shipping 10
6:49 PM: John Beck(Ins): Hi, Theodora. We are on Ch 3, p13.
6:49 PM: Lindsay Gardner: oh thats' why we get the 13
6:49 PM: Theodora Soriano: thank you
6:49 PM: Tynese Harris: ooohh
6:49 PM: John Beck(Ins): 2 + 2 + 6 = 10
6:49 PM: Anna Oster: ok
6:50 PM: Justin Ambrose: we already picked out 4 bad computers so we need 6 good ones right?
6:50 PM: Brandis Lee: gotcha
6:50 PM: John Beck(Ins): Right, Justin!
6:50 PM: Justin Ambrose: its that easy? I have been racking my brain all week
6:50 PM: John Beck(Ins): Then we multiply. Go to page 14, please.
6:50 PM: Jamie Baldwin: lol
6:51 PM: Tynese Harris: wow...
6:51 PM: John Beck(Ins): Racking your brain is good, Justin.
6:51 PM: John Beck(Ins): Go to page 15, pleas.
6:51 PM: John Beck(Ins): e
6:52 PM: Theodora Soriano has left the room.
6:52 PM: John Beck(Ins): Tonight's chat is short. This week's lesson is long, and complicated!!!!!!
6:52 PM: Brandis Lee: our test is on only these three chapters though right
6:52 PM: Tynese Harris: yes it is
6:53 PM: John Beck(Ins): Class, I'll be the first to admit that this week's lesson is complicated.
6:53 PM: John Beck(Ins): No, Brandis, Test 1 covers ch 1, 2, 3, and 4.
6:53 PM: Theodora Soriano has entered the room.
6:53 PM: John Beck(Ins): HI again, Theodora.
6:53 PM: Brandis Lee: hahah was hoping to get off easy here
6:53 PM: Theodora Soriano: sorry my computer kicked me off & I had to log on again
6:53 PM: Lindsay Gardner: Why is it complicated? Doesn't it cover whay you just showed us this evening?
6:53 PM: Jamie Baldwin: thats funny
6:53 PM: John Beck(Ins): It happens to all of us, Theodora.
6:54 PM: John Beck(Ins): Yes, Lindsay, but it is complicated.
6:54 PM: John Beck(Ins): Okay, Class, any questions?
6:54 PM: Jamie Baldwin: not that i have from what we covered
6:55 PM: Shante Jackson: not yet
6:55 PM: Anna Oster: no, thank you Professor
6:55 PM: John Beck(Ins): Don't forget that you can email me with questions!!!!!!
6:55 PM: Brandis Lee: I just want to go over why we choose combinations over permutations
6:55 PM: Tynese Harris: not now...but may have some questions later
6:55 PM: John Beck(Ins): Brandis, the short answer is that
6:55 PM: Theodora Soriano: that is a good question, I want to learn how to differentiate those in word problems
6:55 PM: Lindsay Gardner: Will the Lesson portion be more in depth, and in turn help us with the homework better?
6:55 PM: Jamie Baldwin: true
6:56 PM: Lindsay Gardner: I had that same question about permutations and combinations too. THey seem to overlap a bit.
6:56 PM: Sammy Ibrahim: none thanks. night
6:56 PM: Sammy Ibrahim has left the room.
6:56 PM: John Beck(Ins): Class, I created the Lessons, so I "think" everything is explained in great detail.
6:57 PM: Lindsay Gardner: Ok, so as long as we take good notes then that should help
6:57 PM: Anna Oster: bye bye
6:57 PM: John Beck(Ins): The short answer is, "We use combinations when order isn't important" and we use permutations "when order is important."
6:57 PM: Anna Oster has left the room.
6:58 PM: Theodora Soriano: o, ok
6:58 PM: John Beck(Ins): When you look at a problem, step back and ask yourself if order is important.
6:58 PM: Brandis Lee: I did but i seemed to get some of the practice answers wrong
6:58 PM: Theodora Soriano: Another ? is for this first test coming up, do we need to bring a calculator (can we use one?) or are they provided? Also, is it open notebook or no notes allowed?
6:58 PM: Brandis Lee: I am off work tomorrow so I will study it more
6:58 PM: John Beck(Ins): For example, when I have a program for a recital, I need to know who is first or second or third, so "order is important. Theodora, it closed book and no notes.
6:59 PM: John Beck(Ins): My program has a computer, Theodora.
6:59 PM: John Beck(Ins): Email me if you have questions, Brandis.
6:59 PM: Theodora Soriano: the test is on computer at the test center
6:59 PM: Brandis Lee: Ok thanks
6:59 PM: Theodora Soriano: ?
7:00 PM: Jamie Baldwin: good question brandis, i think everyone was a tad confused
7:00 PM: John Beck(Ins): Taking good notes and "thinking" about what you just did to solve a problem is the key.... I hope.,
7:00 PM: Heather Rawls has entered the room.
7:01 PM: John Beck(Ins): Yes, Theodora, you will need to go to the testing center to take the tests. The tests are online, but they have the URL and the password.
7:01 PM: John Beck(Ins): Okay, Class, email me if you have questions!
7:01 PM: John Beck(Ins): G'night
7:01 PM: Jamie Baldwin: night
7:01 PM: Theodora Soriano: thank you

7:56 PM: Lisa Thomas: im just hoping that i will do ok on the upcoming test, that is my biggest problem. i am a terrible test taker. i just go into panic and freeze mode, hope we get points for the correct date and name. lol. then i will at least get some credit.
