    If you randomly pick numbers from 1-100 without them being emliminated after they're hit, is there a better chance of it picking a constant number each time, say 33, or a better chance it will hit a constantly changing number? Understand?

    To elaborate on that, what if the number was eliminated after it was hit?

    you mean integers from 1-100?
    I don't quite understand the question:
    do you mean: is the probability of hitting the same # twice after each other greater than hitting a different one each time?
    or do you mean: if you choose some constant (say 50) of these #s, is the probability of the sum being some # higher than others?
    or did you mean something completely different, ...?

    Say you pick 1 million numbers randomly between 1 and 100. Then, out of the 1 million numbers, you should find that each number occurs approximately 10000 times. So, if you look at, say, the number 53, you should find it popping up about 10000 times in total. But that could happen in many different ways. For example, you might get 53 one hundred times in a row, then a few sprinkled 53s in the following 9999900 picks, enough to make about 10000 in total.

    James R understood the question. Thanks, that what I thought but I didn't know how to prove it.

    It's the definition of randomly selecting something. Now, it also depends upon how you're randomly picking numbers. A friend of mine did a little research project on random number generators and found that some algorithms are "more random" than others.
