Question

A number is selected at random from first 50 natural numbers. Find the probability that it is a multiple of 3 and 4.

Answer 1

Total no. of possible outcomes = 50 {1, 2, 3 …. 50}

No. of favourable outcomes = 4 {12, 24, 36, 48}

P(E) =`"No.of favorable outcomes"/"Total no.of possible outcomes"`

P(E) = 4/50 = 2/25
