Statistics - Poisson distribution.

  1. Jun 15, 2009 #1
    (Not sure if I should have posted this in the h/w problem section since it's not really hw...just a problem I've faced recently. But if it should be there, I can move it there. )

    There are 5 boxes.

    Each box may contain a certain amount of marbles (1, 2, 3 etc.) and some have no marbles at all. You know that 2 of the 5 boxes contain no marbles at all. No other information is given.

    Using the poisson distribution, approximately how many marbles are there estimated to be total in the 5 boxes?

    How would any of you guys would go about solving this problem?

    Nevermind, I figured it out.

    Not sure how to delete this post though...
