Question

The waiting time at a doctor’s office is uniformly distributed with a minimum waiting time of 10 minutes and a maximum waiting time of 30 minutes. What is the probability that a person has to wait between 10 and 15 minutes?

Answer 1

25%

Explanation:

There are 20 minutes between 10 and 30 and 5 minutes between 10 and 15 so you need to find 5% of 20 (5/20 x 100) which is 25%
