There is no replacement.
(a) 130/400 * 129/399 * 128/398
This should give you an idea of how to proceed with the remaining problems.

I have this very question and I am in my last year of college taking math as my last class after 4 years of college because it is challenging for me so that statement is incorrect it is a COLLEGE question!
Shut up Ms. Sue
Shut. Up.

The SUBJECT shouldn't be "college", it should be 'MATH'. How does kay expect to get help when when she doesn't say what subject she needs help in?
Tanya you're slow..

a) P(choosing 3 women)= 130C3/400C3=0.03
b) P(choosing 2 women)=(130C2)(270C1)\400C3
b) P(choosing 2 women)=(130C2)(270C1)\400C3
