Question You are dealt a 13 card bridge hand from a 52 card bridge deck.
a. What is the probability that you will be dealt exactly 5 hearts?
b. What is the probability that you will be dealt at least 2 hearts?
c. What is the probability that you will receive 5 hearts, 4 clubs, 2 diamonds, and 1 spade?
Answer This is a basic choice problem. If the are N items with n defective, what's the chance of getting m wrong in a draw of size M. Take (a,b) to be a choose b.
The answer is (M,m),(N-M,n-m)/(N,n).
On all, N=52 and n=13.
On a., m=5. On b., m=2. On c., there are four factors on top: (13,5), (13,4), (13,2), and (13,1) which are multiplied together before being divided by (N,n).
