The probability that a number selected at random from the first 50 natural numbers is a composite number is ? Choose the correct option
A) 17/28 B) 17/25 C) 17/17 D) 17/19 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
