    Exclamation Which method to solve...

    I just need direction...which method do I use to solve these two problems...

    1) 2011 NYC had such and such number of accidents between Mon-Fri, corresponds to 14.4/hr.
    a) Compute the probabilty of at least 1 accident in a certain number of mins
    b) What's the prob that 4 or more accidents happened during that same period of time

    the next problem is similar I think...do I use the Hypergeometric probability function?

    I should have started on this sooner, but with a new baby and my back up help sick - I'm trying to work on this and tend to the baby...fun fun, right?

    I was thinking Poisson distribution, since hypergeometric is successes and you seem to have counts. I believe that the Poisson may tend toward the normal distribution when the average is 8 or greater.
