The probability that a number selected at random from the first 50 natural numbers is a composite number is?	Choose the correct choice from the following answers:  A) 17/29  B) 17/21  C) 17/22  D) 17/29  E) 17/25
The number of exhaustive events = 50C1 = 50.   We have 15 primes from 1 to 50.   Number of favourable cases are 34.   Required probability = 34/50   = 17/25.   Answer: 17/25
