Question 1101704: Which of the following statements about a discrete random variable and its probability distribution are true?

Some negative values of P(X) are allowed as long as ∑ P(X) = 1.

The values of P(X) increase to a maximum point and then decrease.

Values of P(X) must be greater than or equal to zero.

Values of the random variable (X) can never be negative
