If the numbers 1 to 98 are written on 98 pieces of paper, (one on each) and one piece is picked at random, then What is the probability that the number drawn is neither prime nor composite?  Choose the correct answer:  A) 1/50  B) 1/25  C) 1/98  D) 1  E) 2
There are 25 primes, 72 composite numbers from 1 to 98. The number   which is neither prime nor composite is 1.   Therefore, required probability = 1/98.   ANSWER:1/98
