WebThe probability mass function, P ( X = x) = f ( x), of a discrete random variable X is a function that satisfies the following properties: P ( X = x) = f ( x) > 0, if x ∈ the support S ∑ x ∈ S f ( x) = 1 P ( X ∈ A) = ∑ x ∈ A f ( x) First item basically says that, for every element x in the support S, all of the probabilities must be positive.

As for any probability distribution, one requires that each of the probability values are nonnegative and the sum of the probabilities over all values of X and Y is one. That is, the function f(x, y) satisfies two properties:

WebMay 25, 2013 · You can't get reliable trustworthy probability data after only one roll. That's why I did 200 rolls. If you want to do it inefficiently , you could set numberOfRolls = 1 and then put the whole code in a loop over the number of rolls (like you tried to do), but this would be a very inefficient, non-MATLAB-ish way of working.
