The function f(x) that defines the probability distribution of a continuous random variable X is a:
A)binomial function.
B)normal function.
C)Poisson function.
D)probability density function.

Question

Quizplus · Accepted Answer

The probability distribution of a continuous random variable is defined by a probability density function (PDF), which is a function that assigns probabilities to intervals of values of X. The PDF of a continuous random variable cannot be a binomial, Poisson, or normal function, as those are specific distributions for discrete random variables or normal continuous distributions. Therefore, the best choice is D, probability density function.
