Question

determine whether the distribution is a discrete probability distribution.
is the distribution a discrete probability distribution? why? choose the correct answer below.
a. no, because the total probability is not equal to 1.
b. yes, because the probabilities sum to 1 and are all between 0 and 1, inclusive.
c. yes, because the distribution is symmetric.
d. no, because some of the probabilities have values greater than 1 or less than 0.

Explanation:

A discrete probability distribution has two key properties: probabilities of all possible outcomes are between 0 and 1 (inclusive), and the sum of all probabilities equals 1. Here, the correct reasoning for a discrete probability distribution is that probabilities sum to 1 and are in the 0 - 1 range.

Answer:

B. Yes, because the probabilities sum to 1 and are all between 0 and 1, inclusive.
