The number of calls that arrive under a particular time in a cell has been established to be a Poisson distribution. The average number of calls arriving in a cell in 1 millisecond is 5. What is the probability that 8 calls arrive in a cell in a given millisecond?

  • Probability and Statistics -

    The average number of events in a 1 ms interval is a = 5.

    Fot m=8 events in that same interval, the probability is
    a^m* e^-a/m!
    = 5^8*e^-5/8!
    =3.906*10^5*6.738*10^-3/4.032*10^4
    = 0.065
