Question

A number is selected at random from the first 35 natural numbers.what is the probability that it is either a multiple of 5 or a multiple of 7..?

Answer 1

Hey friend, ☺️ here is your answer _____________________________

Total outcomes = 35
Favourable outcomes of getting a multiple of 5 or a multiple of 7 = 11 ( 5, 7, 10, 14, 15, 20, 21, 25, 28, 30, 35)

P(x) = Favourable outcomes / total outcomes
P( getting a multiple of 5 or 7) = 11/35

Hope this helps you...
