Question

A discrete probability distribution: a. is a tool that can be used to incorporate uncertainty into models b. is the distribution of a single random variable c. can be estimated from long-run proportions d. lists all of the possible values of the random variable and their corresponding probabilities

Answer 1

Answer: D. Lists all of the possible values of the random variable and their corresponding probabilities.

Step - by - step explanation:

In statistical studies, a probability distribution relates the result of a study/event with the probability of its occurrence. For example, we can ascertain that the probability of getting 1, 2, or 3 tails when we toss a coin is 0.1, 0.2, or 0.3.

While Continuous probability distribution lists the probabilities of values that cannot be counted, Discrete probability distribution gives the probabilities of exact values.

Answer 2

Option d

Explanation:

A discrete probability distribution depicts the probability distribution of a discrete random variable whereas discrete random variable is the variable with countable values. So, the discrete random variable takes value as 0,1,2,3,...

A probability distribution represents the probabilities of every possible value of random variable. Thus, a discrete probability distribution contains lists all of the possible values of the random variable and their corresponding probabilities.
