Question

Define probability. Each number from 1 to 20 is written on a slip of paper and placed in a hat. If a slip of paper is randomly-chosen from the hat, determine the probability that a prime number will be selected.

Answer 1

What the person above me said i believe is factually correct?

Answer 2

I believe that the answer is the addition of all the prime numbers as numbers themselves
Like 1 3 5 7 11 13 17 19 would be 9 numbers so 9/20
