The probability that a number selected at random from the first 50 natural numbers is a composite number is ?	Choose the correct answer
A) 17/26
B) 17/25
C) 17/21
D) 17/28
E) 17/12
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
