    p(A) = [A/A0^2]exp[-{A^2/2*A0^2}], A>= 0

    1. Average (Mean)
    -------------

    Integral (A=0 to infinity)[A*p(A) dA]
    = (1/A0^2)*Integral (A=0 to infinity)[A^2exp{-(A^2/2*A0^2)} dA

    Now from standard Integral table we get,

    Integral (x=0 to infinity)[x^2exp{-(a*x^2)} dx = (1/4a)sqrt(pi/a)

    Here a = ...
