A committee of seven people is to be selected from a group of 10 men and 8 women. What is the probability that the committee will be made up of:
a. three men and four women?
P(3 men and 4 women) = [10C3*8C4]/[18C7]
------------------------
b. P[at least six men] = [10C6*8C1+10C7]/[18C7]
----------------------
c. P[at least two women] = [8C2*10C5+8C3*10C4+8C4*10C3...+8C7]/[18C7]
-------------------------
etc.
