In a contest, a bowl contains 6 keys, one of which will open a treasure chest and Five of which will not. If a contestant selects the key that opens the treasure chest, she wins the contents of that chest. If Kishore is allowed to draw two keys, simultaneously and at random, from the bowl as the first contestant, what is the probability that he wins the prize?	Choose the correct choice:  A) 1/2  B) 1/3  C) 1/4  D) 1/5  E) 1/6
The total possibilities existing while withdrawing two keys are: 6C2 = 15   For Kishore to win, 5 combinations exist assuming Key 1 to unlock the treasure E.g(1,2), (1,3)....(1,5)   P = 5/15= 1/3   Option 1/3
