Answer to Question #36001 in Statistics and Probability for Lisa

Question

I have a pool of 3000 people. I need 5% of that pool randomly selected in the result set.
If I run my code, assigning a random number then pulling the Top 5%.

I seem to get some of the same people in the result set each time I run my code.

What is the probability or odds of this happening?

Thank you for any help you can offer.
