From a recent statistical analysis for the last five years, on an average there
are 4 (major) air accidents per month in the world. Let X be the number of air accidents occurred in a randomly selected month. It is known that X ~ Poisson() approximately, where the intensity   4 accidents (monthly average number of accidents). Find the probability that there will be 4 or more air accidents

    Sooo...I see you are having problems with this too! LOL

    Try the Poisson Distribution.

    Poisson distribution (m = mean):
    P(x) = e^(-m) m^x / x!

    Values:
    x = 0,1,2,3
    m = 4

    Calculate P(0), P(1), P(2), P(3). Add together, then subtract that value from 1. This will be your probability.

    I hope this will help get you started.
