Answer:answer is there below
Step-by-step explanation:
The easy, and somewhat wrong, answer is 6/20. There are six multiples of 3 in the range after all, and 20 numbers (assuming 1 and 20 are included).
Why is it somewhat wrong? Because the distribution wasn’t specified.
For an obvious example of why this matters, let’s say we were instead asking
“Choose a number between 2 and 12, what is the probability that the number is a multiple of 3?”
That could be uniform, each number having the same chance of being picked… But it could also be the sum of two six-sided dice.
