The probability that a number selected at random from the first 50 natural numbers is a composite number is?
Select the correct option:
A) 17/65
B) 17/25
C) 17/28
D) 17/65
E) 17/39
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
