A table,formula,or graph that shows all possible values a random variable can assume,together with their associated probabilities,is called a(n) :
A) probability distribution.
B) discrete random variable.
C) expected value of a discrete random variable.
D) None of these choices.
Discrete Random Variable
A variable that can take on a countable number of possible values, often representing counts or categories.
Expected Value
The long-run average or mean value of random variables, indicating the anticipated outcome of an experiment if it were repeated many times.
