The distribution of probabilities for each outcome of a random variable that sums to 1.00 is called a
A) random variable.
B) probability distribution.
C) conditional probability.
D) sample space.

Quizplus · Accepted Answer

A probability distribution is a way to describe the likelihood of different outcomes for a random variable. It shows the probabilities of each possible outcome, and these probabilities must sum to 1.00. Therefore, B is the correct choice. A random variable refers to a numerical outcome of a random process, but doesn't necessarily include the probabilities associated with those outcomes. Conditional probability refers to the probability of an event given that another event has occurred, but again doesn't describe the entire distribution of probabilities. Sample space refers to the set of all possible outcomes for a random process, but doesn't specify the probabilities associated with each outcome.
