The amount of time it takes Ariana to do a math problem is continuous and uniformly distributed between 38 seconds and 79 seconds. What is the probability that it takes Ariana between 58 and 70 seconds to do a math problem

29.27% probability that it takes Ariana between 58 and 70 seconds to do a math problem

Step-by-step explanation:

An uniform probability is a case of probability in which each outcome is equally as likely.

For this situation, we have a lower limit of the distribution that we call a and an upper limit that we call b.

The probability that we find a value X between c and d, d being greater than c, is given by the following formula:

Uniformly distributed between 38 seconds and 79 seconds.

This means that
