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