Wartman III: hi edie!
7:45 PM: John
Beck(Ins): Oops, tonight's
chat session is very short.
7:45 PM: Edith
Panzarella: hi Kenny!
7:45 PM: John
Beck(Ins): How many of you
have noticed that there is a practice test for Test 1 on my website?
7:46 PM: Hollynn
VanCourt: I did
7:46 PM: Hollynn
VanCourt: I think I printed
it out
7:46 PM: Edith
Panzarella: I think I saw it
7:46 PM: John
Beck(Ins): There is both a
print version and an online version.
7:46 PM: John
Beck(Ins): I recommend that
you use both.
7:46 PM: Hollynn
VanCourt: ok
7:47 PM: Donna
Brown-Green: great!
7:47 PM: Amy Matheny has entered the room.
7:47 PM: John
Beck(Ins): When you go to the
testing center, you'll be taking the test online so you should be familiar with
how my tests are constructed.
7:47 PM: Mary Stilling: OK
7:47 PM: John
Beck(Ins): Hi, Amy!
7:47 PM: Edith
Panzarella: we go to a testing
center, correct?
7:47 PM: Amy Matheny: hi
7:47 PM: Hollynn
VanCourt: do we need school
ID at the testing center?
7:47 PM: John
Beck(Ins): Yes, Edie, you'll
have to go to one of the testing centers four times this semester.
7:47 PM: John
Beck(Ins): I think that all
of the testing centers require a picture ID.
7:48 PM: John
Beck(Ins): I'm not certain
whether they require a school ID or whether they will accept a driver's license.
7:48 PM: John
Beck(Ins): license
7:49 PM: John
Beck(Ins): When you call for
your appointment you should ask about the "picture ID" requirement.
7:49 PM: Hollynn
VanCourt: ok, I'll call and
double check
7:49 PM: John
Beck(Ins): Okay, Class, let's
get started.
7:49 PM: Amy Matheny: They will take a drivers license, I
have been before
7:49 PM: Hollynn
VanCourt: Thanks!
7:49 PM: John
Beck(Ins): Let me know when
you are on Ch 3_p1, please.
7:49 PM: Mary Stilling: I am
7:49 PM: Hollynn
VanCourt: I am, too
7:50 PM: Edith
Panzarella: me too
7:50 PM: Amy Matheny: me too
7:50 PM: Kenneth
Wartman III: Am there.
7:50 PM: Donna
Brown-Green: ready
7:50 PM: John
Beck(Ins): Go to page 2,
please.
7:50 PM: John
Beck(Ins): Notice we could
just list all the one thousand possible Pick 3 numbers.
7:51 PM: John
Beck(Ins): Or we could use
MATH 111 to determine the possible outcomes.
7:51 PM: John
Beck(Ins): Go to page 3,
please.
7:51 PM: John Beck(Ins): Go to page 4, please.
7:51 PM: John
Beck(Ins): If you've seen
this on TV, there are 3 urns with 10 balls in each urn.
7:52 PM: John
Beck(Ins): Their balls jump
around. Mine are sitting there waiting to be drawn.
7:52 PM: John
Beck(Ins): Go to page 5,
please.
7:52 PM: John
Beck(Ins): There are 10
possible outcomes when we draw a ball from the first urn.
7:52 PM: John
Beck(Ins): So n sub 1 is
equal to 10
7:52 PM: John
Beck(Ins): Go to page 6,
please.
7:53 PM: John
Beck(Ins): There are 10
possible outcomes when we draw a ball from the second urn.
7:53 PM: John
Beck(Ins): So n sub 2 is
equal to 10
7:53 PM: John
Beck(Ins): Go to page 7,
please.
7:54 PM: John
Beck(Ins): There are 10 balls
in the third urn, so there are 10 possible outcomes when we select a ball from
the 3rd urn.
7:54 PM: John
Beck(Ins): Go to page 8,
please.
7:54 PM: John
Beck(Ins): Notice we
multiplied 10 by 10 by 10.
7:54 PM: John
Beck(Ins): Go to page 9,
please.
7:55 PM: John
Beck(Ins): At this point I
always say, if we knew which computers would have problems, we'd fix them.
7:55 PM: John
Beck(Ins): Go to page 10,
please.
7:55 PM: John
Beck(Ins): Go to page 11,
please.
7:56 PM: John
Beck(Ins): Three of the
computers have video card problems and we are going to select 2 of them.
7:56 PM: John
Beck(Ins): Go to page 12,
please.
7:56 PM: Kenneth
Wartman III: Question.
7:57 PM: Barbara
Mierzwa has entered the
room.
7:57 PM: Susie Brooks has entered the room.
7:57 PM: Barbara
Mierzwa: sorry I’m late!!!
good evening!!
7:57 PM: John
Beck(Ins): 4 of the computers
have hard drive problems so we use C(4,2)
7:57 PM: Kenneth
Wartman III: To get the answers
for n1 , n2, and n3 , do we use the factorial stuff to work it?
7:57 PM: John
Beck(Ins): Hi, Barbara!
7:57 PM: John
Beck(Ins): Barbara, we are on
Ch 3_p12
7:58 PM: Susie Brooks: Not easy to get in tonight
7:58 PM: John
Beck(Ins): Yes, Kenneth
7:58 PM: Kenneth
Wartman III: Ok, thank you.
7:58 PM: John
Beck(Ins): In this chapter
we'll be using Combinations and Permutations.
7:58 PM: John
Beck(Ins): Go to page 13,
please.
7:58 PM: John
Beck(Ins): There are 13
computers that don't have any problems, and we need to choose 6 of them, so we
have C(13,6)
7:58 PM: John
Beck(Ins): \Go to page
14,please.
7:59 PM: John
Beck(Ins): Once again, we're
multiplying!
7:59 PM: John
Beck(Ins): Go to page 15,
please.
7:59 PM: John
Beck(Ins): Last week we
mentioned "Fundamental Counting Principle"
7:59 PM: John
Beck(Ins): This week we get
to use it
7:59 PM: John
Beck(Ins): Over
7:59 PM: John
Beck(Ins): And
7:59 PM: John
Beck(Ins): Over
7:59 PM: John
Beck(Ins): Again;
8:00 PM: John
Beck(Ins): You’re going to
break big problems down into small problems.
8:00 PM: Kenneth
Wartman III: Can you please
explain the difference between permutations and combinations?
8:00 PM: John
Beck(Ins): Then we're going
to multiply!
8:00 PM: John
Beck(Ins): Piece of cake!!!!!
8:01 PM: John
Beck(Ins): For situations
where order isn't important, we use combinations.
8:01 PM: John
Beck(Ins): If order is
important, we use permutations.
8:01 PM: Kenneth
Wartman III: Oh ok. Thank you!
8:01 PM: John
Beck(Ins): You have to look
at a situation and ask yourself if order is important
8:01 PM: John
Beck(Ins): Sometimes it is
obvious, but other times it is subtle.
8:02 PM: Kenneth
Wartman III: So like choosing a
president, vice president, and secretary would be important?
8:02 PM: John
Beck(Ins): Yes!
8:02 PM: Kenneth
Wartman III: Oh ok
8:02 PM: Kenneth
Wartman III: But to select 7 members
of a committee isn’t important to order.
8:02 PM: John
Beck(Ins): That's right
again!
8:02 PM: Kenneth
Wartman III: Okay, kewl. Sorry
for all the questions :)
8:03 PM: Kenneth
Wartman III: Just making sure I
have this straight.
