probability
double probability(double x)
For a random variable X whose values are distributed according to this distribution, this method returns P(X = x). In other words, this method represents the probability mass function, or PMF for the distribution.- Parameters:
x
- the value at which the probability mass function is evaluated.- Returns:
- the value of the probability mass function at x
