  1. You get something close to that either way. What I want to know is if one person has more than one entry what the effect on the odds would be.
  2. Correct, there is no benefit to being drawn first. Once, a winning entry is drawn then the prize and that number is gone from the pool. Additionally, nobody has the same number.
  3. Well, I am treating all prizes as being equal for the sake of simplicity. So all 500 prizes are effectively the same thing. And for the sake of an overall chance of winning I have combined them.
  4. Hi guys, Currently, trying to determine the percentage chance of winning an imaginary giveaway for 500 prizes. It uses a single entry per person. Say there is 10000 entries and a total of 500 can win with each winner being unique (1 per person). So far I figure that since you can only win once the odds would be: 1/10000 + 9999/10000 * 1/9999 + 9999/10000 * 9998/9999 * 1/9998 + 9999/10000 * 9998/9999 * 9997/9998 * 1/9997 + ... etc How would I go about calculating that if one person was to have 1000 entries instead of just one? For example, say one person cheats and gets 1000 tickets in a raffle instead of just one with the same prize pool and total entries.
