Dear Tablepooey, I initially noted that I understood your solution, by noting that you based it on n!/r!(n-r)! to limit the products (the probabilities). Ie, the number of ways to draw a particular ticket 6 times in your example of 100 draws. Then I noted that you didn't even follow through with your very own example because it couldn't have made any sense. I didn't write that your solution wasn't an estimate. I wrote that it was simply wrong given the true nature of the problem, which amounts to taking the drum as a whole, not, to the probability of drawing a particular ticket. So, your latest attempt is just more mud against the barn door. If you still can't see it, then post the question on a real math forum, and, then, see what happens. I didn't post a real solution because this is what happens on a gambling forum.
P.S. You should and ought to have looked up something, for yourself. Here's the first thing that popped up about solutions being proofs. Sort of an "estimate of an inscribed subproof" that has the word proof, and, then, in brackets, the word, solution. And the numeral, 42. Give it a click, looks sort of academic in nature.
Lol.
