    A marina hires out boats on a daily basis, the mean number of boats hired per day is 15. Using a normal approximation for a poisson distribution find for a period of 100 days:
    a)How often 5 or less boats are hired
    b)How often 10 boats are hired
    c)How many times will customers have to be turned away if only 20 boats are owned.

    This is what I can remember from the top of my head - it may well be wrong !!!
    X~Po(15), but for 100 days X~Po(1500)
    Y~N(1500,1500)

    hmmmmmm, do the questions mean per day or in 100 days??

    yeah, it is very bizarre that it should want you to model it for 100 days, what is the point?! I shall have a think, but something tells me I'm not gonna get very far, I really do not like stats!
    Sorry !!
