Question

Problem 84b

Answer 1

Given information

A fireworks show is designed so that the time between fireworks is between one and five seconds, and follows a uniform distribution.

Step-by-step explanation

Step 1.

As given in the problem the data is as follows:

.

Here, the least value , the highest value .   

The Height of probability distribution can be calculated as follows:

 

The required probability is the area under the curve, therefore

 

Therefore, the probability that the time between fireworks is greater than four seconds is

.
