    Propability function of |x-y|

    Hello everybody.

    I need a little help.
    If x
    is a variable and X(m1,σ1) its propability function (normal)
    and y another
    variable and Y(m2,σ2) its propability function (normal),
    what if the
    propability function of |x-y| and what kind of distribution is it?
    I know it
    is not normal since |x-y|>0.

    Thanks in advance.
