pullpmf function (and consequently cmf) do not return proper results

Works properly for 0 <= n < 75 but anything n >= 75 gives nonsense responses (negative answers and answers above 1 are not within its range).

Additionally, pullpmf is not functionally useful for future commands. Command should be overhauled to simply be a piecewise function that shows probability

p is supposed to be 0.006, 0.06. Function still needs rewriting.
