Assume that you have 11 mice in the cage: 3 white males, 5 gray females, and 3 gray males. two mice are selected simultaneously and at random, and their colors are noted. what is the probability that at least one mouse is female, given that exactly one is gray?

5/8

Explanation:

Since exactly one is grey than one is white. And only one can be female that is grey one.

therefore, the probability that at least one mouse is female, given that exactly one is gray

=5/8

you probably know the answer. stop asking stupid questions and making me waste my time. j.k. ; )   b.t.w. what are three ratios equivalent to 5 : 11? thx

answer; all of the above are correct;
