Calculates the Binomial Distribution Probability Mass Function.
pmf: The result of the formula. 0<= pmf <=1
sccs: The number of successful trials. Only the integer part is used. 0 <= sccs <= trials.
trials: The total number of trials. Only the integer part is used. 0 <= trials
prob: The probability of success for each trial. 0<= prob <=1
Sports team A has a 0.6 probability of beating team B in any given game. If they play 4 games, what is the probability of team A winning exactly 4 of the 4 games?
