Okay, so we have music club and softball club, and i've just used the initials to denote the people in each.
00:09
And this problem came through kind of garbled.
00:13
I think this is the way the problem is set up.
00:18
If it's not, just follow my logic, and you can still answer the questions just by moving people appropriately.
00:24
Appropriately.
00:26
So the first thing, okay, so music is a, event a, and softball is event b.
00:39
And just to help, let's just put a venn diagram.
00:45
So we'll call this a, and we'll call this b.
00:53
And, oh, and there's a debra too, who's in neither, i guess.
01:02
So i don't see the venn diagram.
01:04
I'm i'm trying to reproduce the venn diagram.
01:07
And again, hopefully i have this right.
01:10
So we have, oops, draw.
01:13
Okay, so we have d outside the venn diagram.
01:16
We have hans and miguel, or h and m, in both clubs.
01:23
And then in the softball and not music are k and as.
01:30
S.
01:31
And in the music and not both is t, a, m, and c.
01:41
One, two, three, four, five, six, seven, eight.
01:45
I'm missing one student.
01:47
One, two, three, four, five, six, seven, eight.
01:50
Let me see.
01:51
I'm missing a student.
01:54
Okay.
01:54
I can't tell by the wording of the question where keisha is.
02:00
So i'm going to put keisha in the softball.
02:07
Again, if that's not right, just move keisha to where she should be, and then you can still answer the questions.
02:15
Okay, because again the venn diagram doesn't, didn't come through in the question.
02:23
So this is, i'm helping you set this problem up, but you may have to move things around.
02:29
Okay, so we're asked, so given my setup i have nine students and we're asked what various probabilities are.
02:43
Okay, number one, it's a probability of a...
