There are 24 red jellybeans in a bag of 140 jellybeans. Let the integers 1-24 represent the red jellybeans in a calculator simulation of the situation that generates random integers from 1-140. A sample of 15 "jellybeans" gives the following: 38, 6, 69, 115, 17, 53, 96, 104, 21, 77, 43, 29, 39, 55, 71.

I don't understand random samples, so please explain.
