  1. #1

    probability of observation




    “In a hospital, births occur randomly at an average rate of 2 births per hour. Calculate the probability of observing
    1. 3 births in a given hour at the hospital.
    2. No birth in a given hour at the hospital."

    Read up on the Poisson distribution and you should be able to work it out. It's probably more important to understand why the Poisson is suitable in this case. The link explains that too.

    1.
    P(x; μ) = (e-μ) (μ^x) / x!
    P(3; 2) = (2.71828-2) (2^3) / 3!
    P(3; 2) = (0.13534) (8) / 6
    P(3; 2) = 0.180

    2. P(0,2)= oh I'm just as lazy as you are
