Due to a negative value of P(X = x), it is found that the following is not a probability distribution.
---------------------
A sequence (x, P(X = x)) is a probability distribution if:
- The sum of all values of P(X = x) equals 1.
- There is no negative values of P(X = x).
In this problem, P(X = 2) is negative, thus, it is not a probability distribution.
