5:59 PM: Roxanne Vendetti has entered the room.
5:59 PM: John Beck(Ins): HI, Roxanne!
5:59 PM: Diana DeJesus-Stinnette: ok
5:59 PM: Roxanne Vendetti: Hello
5:59 PM: DeAnn Blatche-Brookshire: Hello!
6:00 PM: John Beck(Ins): Let's get started. Let me know when you are on Ch 3_ p1, please.
6:00 PM: Heather Cate: ready
6:00 PM: Diana DeJesus-Stinnette: k
6:00 PM: Roxanne Vendetti: yes
6:01 PM: Victoria Pearce: ok
6:01 PM: John Beck(Ins): Are you with us, DeAnn?
6:01 PM: DeAnn Blatche-Brookshire: yes
6:02 PM: John Beck(Ins): Okay, let's go to page 2, please.
6:02 PM: John Beck(Ins): One way to find out how many possibilities would be to try to list all the possible outcomes.
6:02 PM: John Beck(Ins): Go to page 3, please.
6:02 PM: Shantiea Smith-Mack has entered the room.
6:03 PM: John Beck(Ins): Hi, Shantiea! We're on Ch 3_p3.
6:03 PM: Shantiea Smith-Mack: Good evening everyone
6:03 PM: John Beck(Ins): Go to page 4, please.
6:03 PM: John Beck(Ins): If you've ever seen this on TV, they have 3 urns with 10 ping-pong balls in each urn.
6:03 PM: Diana DeJesus-Stinnette: yes
6:04 PM: John Beck(Ins): Before we go any further, notice that 000 is one of the possible outcomes. Could we use combinations or permutations to solve this problem?
6:04 PM: Roxanne Vendetti: combinations?
6:04 PM: Heather Cate: comb.
6:04 PM: DeAnn Blatche-Brookshire: combi
6:04 PM: Diana DeJesus-Stinnette: I would say combination
6:04 PM: Victoria Pearce: comg
6:04 PM: Julie Occhionero has entered the room.
6:05 PM: John Beck(Ins): Notice that we have 0 as our first number, 0 as our second number, and 0 as our third number.
6:05 PM: John Beck(Ins): Hi, Julie! We're on Ch 3_p4
6:05 PM: John Beck(Ins): Notice that I've repeated the number zero.
6:05 PM: Julie Occhionero: Hello. Thank you. I'm at work, but I'll try to keep up.
6:05 PM: Shannon Thomas has entered the room.
6:06 PM: John Beck(Ins): Is repetition allowed in combinations and permutations.
6:06 PM: Roxanne Vendetti: true so neither would work
6:06 PM: Victoria Pearce: no
6:06 PM: John Beck(Ins): Hi, Shannon! We're on Ch 3_p4.
6:06 PM: John Beck(Ins): That's okay, we've got lots of tools.
6:06 PM: John Beck(Ins): Go to page 5, please.
6:06 PM: Shantiea Smith-Mack: No reputition is not allowed
6:06 PM: John Beck(Ins): Right, Shantiea.
6:07 PM: Shannon Thomas: ok, i am having trouble on my pc, so i am on my mac. i cant access the walktru on the computer i am on right now. working on it
6:07 PM: John Beck(Ins): What we're going to do is break this problem into 3 parts.
6:07 PM: John Beck(Ins): parts.
6:07 PM: Heather Cate: ok
6:07 PM: Diana DeJesus-Stinnette: k
6:07 PM: John Beck(Ins): The first part is to determine how many possible outcomes we have when we select a ball from the first urn.
6:07 PM: John Beck(Ins): Notice that there are 10 possible outcomes.
6:08 PM: Diana DeJesus-Stinnette: yes
6:08 PM: Roxanne Vendetti: yes
6:08 PM: John Beck(Ins): Any of the 10 balls in that urn could be selected.
6:08 PM: John Beck(Ins): Go to page 6, please.
6:08 PM: John Beck(Ins): There are 10 balls in that urn so there are 10 possible outcomes when we select a ball from that urn
6:08 PM: DeAnn Blatche-Brookshire: k
6:08 PM: John Beck(Ins): Go to page 7, please.
6:09 PM: John Beck(Ins): And there are 10 possible outcomes when we select an ball from the urn
6:09 PM: John Beck(Ins): Go to page 8, please.
6:09 PM: Victoria Pearce: my screens cut off in the walkthru
6:10 PM: John Beck(Ins): The Fundamental Counting Principle says we should multiply.
6:10 PM: John Beck(Ins): Victoria. Where is it cut off?
6:10 PM: Victoria Pearce: the very bottom i see little blue pieces but cant tell what they are
6:11 PM: Victoria Pearce: never mind fixed it, just had to adjust the screen
6:11 PM: John Beck(Ins): It is 10 times 10 times 10 which equals 1000
6:11 PM: John Beck(Ins): Is everybody with me?
6:11 PM: DeAnn Blatche-Brookshire: yes
6:11 PM: Diana DeJesus-Stinnette: yes
6:11 PM: Victoria Pearce: yeah
6:11 PM: Shantiea Smith-Mack: Yes Sir!
6:11 PM: Heather Cate: ok
6:11 PM: Roxanne Vendetti: yes
6:12 PM: John Beck(Ins): Okay, let's go to page 9, please.
6:12 PM: Alexandria Hawkins has entered the room.
6:13 PM: John Beck(Ins): Our bigger picture is to ship 10 computers, but we're going to break that down into 3 smaller problems.
6:13 PM: John Beck(Ins): Hi, Alexandria! We're on Ch 3_p9.
6:13 PM: John Beck(Ins): Go to page 10, please.
6:13 PM: Alexandria Hawkins: Hello and thanks
6:14 PM: Katiana Pluviose has entered the room.
6:14 PM: John Beck(Ins): Our first problem will be to determine how many ways we can find 2 computers with video card problems.
6:14 PM: John Beck(Ins): HI, Katiana! We're on Ch 3_p10
6:15 PM: John Beck(Ins): Go to page 11, please.
6:15 PM: John Beck(Ins): Three of our computers will have video card problems, so we need to select 2 computers from that pool of 3 computers.
6:15 PM: DeAnn Blatche-Brookshire: k
6:16 PM: John Beck(Ins): Notice I've used Combinations.
6:16 PM: Heather Cate: yes
6:16 PM: Brandi Smith has entered the room.
6:16 PM: Shannon Thomas: because it doesn't matter which 2 of the 3?
6:16 PM: John Beck(Ins): Hi, Brandi! We're on Ch 3 P11
6:16 PM: John Beck(Ins): Right, Shannon.
6:16 PM: Shannon Thomas: ok
6:16 PM: John Beck(Ins): But more importantly, order isn't important.
6:16 PM: Diana DeJesus-Stinnette: ok lil confused
6:17 PM: John Beck(Ins): Suppose these 3 computers have these serial numbers: 00141, 00142, and 00143
6:17 PM: Diana DeJesus-Stinnette: ok
6:17 PM: Roxanne Vendetti: ok
6:17 PM: Shannon Thomas: that is my only problem with this is determining when to use combinations and when to use permutations
6:17 PM: John Beck(Ins): We could ship the computers with 00141 and 00143
6:17 PM: Diana DeJesus-Stinnette: ok
6:17 PM: John Beck(Ins): Would it be different if we shipped the computers with 00143 and 00141?
6:18 PM: DeAnn Blatche-Brookshire: no
6:18 PM: John Beck(Ins): Right, order isn't important.
6:18 PM: John Beck(Ins): Okay, let's go to page 12,please.
6:18 PM: John Beck(Ins): Four of our computers are going to have hard drive problems.
6:18 PM: Diana DeJesus-Stinnette: I to get confused on when to use permu... and combi
6:19 PM: John Beck(Ins): We need to select 2 from that group of computers.
6:19 PM: Brandi Smith: hello?
6:19 PM: John Beck(Ins): Diana, in general it is when order is important. For example in horse races.
6:19 PM: Diana DeJesus-Stinnette: yes
6:19 PM: Brandi Smith: I can not see the chat on my computer.
6:20 PM: Diana DeJesus-Stinnette: So since order is not important here we use combi
6:20 PM: John Beck(Ins): Another example would be when I arrange couples in a picture -- I might say, "my cousin is the fourth from the left." Notice the order?
6:20 PM: John Beck(Ins): Right, Diana.
6:20 PM: DeAnn Blatche-Brookshire: yes
6:20 PM: Diana DeJesus-Stinnette: ok
6:20 PM: John Beck(Ins): Go to page 13, please.
6:20 PM: John Beck(Ins): please.
6:21 PM: John Beck(Ins): Hmmm. Where did the 13 come from?
6:21 PM: Heather Cate: no clue!
6:21 PM: Victoria Pearce: all the computers left with no problem
6:21 PM: Shantiea Smith-Mack: EXACTLY????
6:21 PM: Shannon Thomas: 20 minus the 3 and the 4
6:21 PM: Diana DeJesus-Stinnette: 13 ???
6:21 PM: John Beck(Ins): RIGHT Shannon!!!!
6:21 PM: DeAnn Blatche-Brookshire: the leftover
6:21 PM: Roxanne Vendetti: 13 is all the computers that work right
6:21 PM: DeAnn Blatche-Brookshire: yup
6:21 PM: John Beck(Ins): Right.
6:21 PM: Diana DeJesus-Stinnette: ohhhhhhh
6:22 PM: Diana DeJesus-Stinnette: ok
6:22 PM: John Beck(Ins): Go to page 14, please.
6:22 PM: Shantiea Smith-Mack: Okay I see now, THANKS!
6:22 PM: John Beck(Ins): Once again, the Fundamental Counting Principle says to multiply.
6:22 PM: John Beck(Ins): Go to page 15, please.
6:23 PM: John Beck(Ins): Guess what, Class?
6:23 PM: Roxanne Vendetti: what?
6:23 PM: Victoria Pearce: were done already?
6:23 PM: Heather Cate: that's it?
