Winning a lottery

  1. Sep 21, 2011 #1
    Hi everyone,
    There is a lottery where in every 100 tickets 10 of them must win. Now, me and my friends want to try. We are 6 and we wish to play such that at least 3 of us win. Can anyone help me and tell me what is the probability that this happen?
    Thank you.

    Hey kthouz.

    Do you mean that you are buying 6 tickets in total and want to find the probability that 3 tickets will come up as a winning ticket?

    Yes that's what I mean
