The set S consists of 5 numbers: {1,2,3,4,5}. If all possible subsets including the null set are created and one subset is chosen at random, what is the probability that the subset has 2 as its largest number?	Choose the correct choice from the following options:
A) 1/2
B) 1/4
C) 1/8
D) 1/16
E) 1/32
The set S has 2^5 = 32 subsets.   The number 2 is the largest number in the subset {1,2} and the subset {2}.   Thus 2 is the largest number in 2 subsets of S.   The probability that 2 is the largest number is 2/32 = 1/16.   The answer is 1/16.
