pmf
If x is not an integer value, then the probability must be zero otherwise pmf(int x) is used to determine the probability
Return
the probability
Parameters
x
the value to evaluate
Returns the f(i) where f represents the probability mass function for the distribution.
Return
f(i) the P(X=i)
Parameters
i
an integer representing the value to be evaluated
Computes the probabilities associated with the range and returns the value and the probability as a map with the integer value as the key and the probability as the related value.
