he probability that a number selected at random from the first 50 natural numbers is a composite number is ?  Choose the correct option:  A) 17/25  B) 4/25  C) 21/25  D) 8/25  E) 9/25
Explanation:   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.   17/25)
