Math Problem Statement

A random variable with an equally likely chance of assuming any value within a specified range is said to have which distribution?

Multiple choice question.

Binomial distribution.

Geometric distribution.

Discrete uniform distribution.

Continuous uniform distribution

Solution

A random variable with an equally likely chance of assuming any value within a specified range is said to have a continuous uniform distribution.

Here's the reasoning:

  • Binomial distribution: This is a discrete distribution that represents the number of successes in a fixed number of independent Bernoulli trials, each with the same probability of success.

  • Geometric distribution: This is a discrete distribution that represents the number of trials needed to get the first success in a sequence of independent Bernoulli trials, each with the same probability of success.

  • Discrete uniform distribution: This is a distribution where each of a finite number of values is equally likely. It is not applicable to continuous ranges.

  • Continuous uniform distribution: This is a distribution where all values within a given continuous range are equally likely. This is the correct answer for a random variable that can assume any value within a specified range with equal likelihood.

So, the correct answer is:

Continuous uniform distribution
