There is a set consisting of 5 numbers--{1,2,3,4,5}. If all possible subsets including null set are created and one subset is picked up, what is the probability that the subset does not have 5 as its largest number?	Select the correct option:  A) 1/5  B) 1/4  C) 1/3  D) 1/2  E) 4/5
Total Number of possible subsets [ including Null Subset ] : 2525 -- (A number can occur or not occur in a subset -- 2 ways)   Possible subsets where 5 is not present [will include null subset] : 24∗124∗1.   P = 2424 / 2525 = 1 / 2.   ANSWER:1/2
