1.there are six employees eligible to be on a three person committee and the manager wantst o know how many different committes are possible. would the manager use a permutation or combination? explain
------
Combinations count groups of objects.
Permutations count arrangements of objects.

Your Problem::
Use a combination:: 6C3 = (6*5*4)/(1*2*3) = 5*4 = 20 ways to choose three.
----------------------------------
2.there are four men and three women eligible for two promotions at a company. if each employee is equally likely to be promoted, what is the probability that both promotions will be given to women? round the answer to the nearest tenth percent.
# of ways to succeed:: 3C2 = 3
---
# of possible pairs:: 7oC2 = (7*6)/(1*2) = 21
----
P(choose 2 women) = 3/21 = 1/7
