Okay, so, I took a few statistics classes back in college but I can never remember a lot of the basics of probabilities. Here's my question:
Say there are two raffles, each of which already have 100 entries with one entry being drawn at random. If I can put two entries down, do I have a better chance of winning anything at all if I put both entries in one raffle or one entry in each raffle? (So it's either a 2/102 chance or two 1/101 chances). How do you calculate that? How about with me putting in more entries, say 20?
