Question

what are the two requirements for a discrete probability distribution?
choose the correct answer below select all that apply
a. ( 0 leq p(x) leq 1 )
b. ( sum p(x)=1 )
c. ( sum p(x)=0 )
d. ( 0 < p(x) < 1 )

Explanation:

For a discrete probability distribution, each probability \(P(x)\) must satisfy \(0\leq P(x)\leq1\) (probability of an event can't be negative or more than 1). Also, the sum of all probabilities \(\sum P(x)\) must equal 1 (as it represents the total probability of all possible outcomes in the sample space).

Answer:

A. \(0\leq P(x)\leq1\), B. \(\sum P(x) = 1\)
