Thank you so much!
You can put this solution on YOUR website! 1. A committee of four people is to be chosen from a group of five women and six men. In how many ways can this be done if:
a. There are no restrictions------11C4 = [11*10*9*8]/[1*2*3*4] = 330
b. The committee is to have exactly two men?----6C2*5C2
c. The committee is to have at most two men?----5C4+5C3*6C1+5C2*6C2
=====================================
2. A jar contains six black and five white marbles. Two marbles are drawn from the jar without replacement. Find the indicated probabilities.
a. P(two white marbles) = 5C2/11C2
b. P(one white and one black marble) = [5C1*6C1]/11C2
====================
