If a number is selected at random from the first 50 natural numbers, what will be the probability that the selected number is a multiple of 3 and 4 ?
Jawaban:
0, 12, 24, 36, 48 … So if “first 50 natural numbers” means the numbers ranging from 1 to 50, then we can see that 4 of those numbers are multiples of 12. So 4/50 = 2/25 = 8% is the probability of a uniformly chosen random number in that range being a multiple of both 3 and 4.
