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
