Bob picks 3 cats. There are 5 striped males, 6 striped females, 8 spotted males, and 4 spotted females.(adsbygoogle = window.adsbygoogle || []).push({});

What is the prob. that Bob has atleast a striped cat given that he has picked at least a female?

------------------------------------------------------

I have:

(prob. of a striped given picked at least a female/total set) / [(Total set-prob of no females)/Total Set]=

(???/23C3) / [(23C3-13C3)/23C3] = ???/(23C3-13C3)

I can't figure out the conditional part though.
