Hi everyone. Say I have a list of 50 items. I pick 10 of them. I put them back. What is the probability that, the SECOND time I pick 10 items, I pick an item I already picked the first time? How about the THIRD time, from the first or second? How about the probability of picking 3 of the same item, or 5? Thanks!
