(m), which must be a real number > 0. x can be an
non-negative integer (SINGLE) or a list of integers
(LIST). The default is mu =1. The probability density
function ( pdf ) is:
Computes a cumulative probability at x for the
discrete Poisson distribution with the specified
mean mu , which must be a real number > 0. x can
be an non-negative integer (SINGLE) or a list of
integers (LIST). The default is mu =1.
