1. ## Probability Problem need help!

Problem: In a company there are 7 executives: 4 women and 3 men. Three are selected to attend a management seminar. Find these probabilities.

A.) All 3 selected will be women

B.) All 3 selected will be men.

C.) 2 men and 1 women.

D.) 1 man and 2 women.

I am not quite sure on how to do this, any help would be great!!

2. hypergeometric

all women ${{4\choose 3}{3\choose 0}\over {7\choose 3}}$

all men ${{4\choose 0}{3\choose 3}\over {7\choose 3}}$

2 men and 1 women ${{4\choose 1}{3\choose 2}\over {7\choose 3}}$

1 man and 2 women ${{4\choose 2}{3\choose 1}\over {7\choose 3}}$
