You are much appreciated. While I have you here and if your up for it, I doubt this is challenging for you but could you check this work. There are 6 males and 4 females awaiting to see a teller at a bank. It is the end of the day and there is only one teller, so only 4 of the people can...

Does it make a difference though that there are three events: A, B, and C. When drawing the Venn Diagram I also have to take event B into consideration also right, or that still does not make a difference.

P[(C U A) n (C n A)] = P(C n A)? (C n A) is a subset of (C U A)? So then the equation would be P(C n A) / P(C n A)? Is that why you said it seems too easy or is this wrong?

That would be, P(F|G) = P(F n G)/P(G) This is the correct question. It is just throwing me off that it is the conditional probability of the union and intersection of two events instead of just the conditional probability of two events. I've gotten as far as: P[(C U A) n (C n A)] / P(C...

Given: P(A)= .4, P(B)=.3, P(A n B)=.11, P(C| not A)=.5 If P(C U A) = .66, then find P[(C U A) | (C n A)]. I have been trying to manipulate this thing for a while now with no luck. Could you try and show the work if not that's alright, I'll work it out. Thanks.

Actually review of an even answer in the text.

HELP! Bankteller Problem Thank you. Could you check this. It is the end of the day and there are 5 tellers, but each teller can only serve one person. Therefore only five people can be served, each by a teller, so the five people are picked at once. 1) How many ways can five of the...

HELP! Bankteller Problem 1. Homework Statement There are 6 males and 4 females awaiting to see a teller at a bank. Only 4 people can be served at one time. 1) How many ways can four of the people be picked and served one at a time, if they must include two(2) men and two(2) women? 2)...

That would be 10c4
