There are four inns in a town. If 3 men check into the inns in a day, then what is the probability that each checks into a different inn?
Choices.
A) 1/6	B) 2/8	C) 3/8	D) 2/3	E) 4/3
Total ways for the 3 men to check into the inns = 4³ ways.   The number of cases where 3 men are checking in different inns = 4 x 3 x 2 = 24 ways.   Therefore, the required probability = 24/4³ = 3/8.   ANSWER:3/8
