    Unhappy [SOLVED] Poisson distribution

    trying to revise for exam on tues by doing some examples,

    company finds that on average there is a claim for damages which it must pay 7 times in 10 years.

    need to find out the probability of at least two claims during the first year.

    ----

    I know how to do the poisson calculations but struggle on the initial figures.

    do i need to divide 10/7 to find the mean for 1 year, which is 1.428571429?

    then use that as e to the minu 1.428571429?

    any help would be great

    The mean number of claims for one year is 7/10, not 10/7. That is the parameter to use for the Poisson distribution.
