Answer:
A. 0≤P(x)≤1
B. ΣP(x) = 1
Step-by-step explanation:
For a discrete probability distribution, the following conditions hold.
0. f(x) must be nonnegative for each value of the random variable x,
,
1. The sum of the probabilities for each value of the random variable must be equal to one.
Therefore, the two requirements are:
A. 0≤P(x)≤1
B. ΣP(x) = 1
