A game is biased such that the choices A-J have the following probabilities of winning:

Question

A=5% B=10% C=15% D=5% E=5% F=25% G=10% H=10% I=10% J=5%

 

If you choose the letters D and H for 20 turns, how many times are you most likely to win?

 

A) 1 time

B)2 times

C) 3 times

D) 4 times 

Answer 1

To find your expected number of wins, multiply the probability of winning by the number of times played.

Together, D & H have a 15% chance of winning.

 

0.15 * 20 plays = 3 wins
