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 choices:
A) 17/28	B) 17/25	C) 17/26	D) 17/22	E) 17/21
: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
