Answer 1

question

a number is selected at random from 50natural numbers find a probability that is multiple of 3 and 4.

Solution

To be a multiple of both 3 and 4 is the same as being a multiple of the “lowest common multiple” or 3 and 4, which is 12 (since 3 and 4 are coprime, and 3 * 4 = 12).

The multiples of 12 go like:

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.
