Expert Solution

Uniform distribution is a type of distribution in which the distribution has a constant probability in some specified interval. It is also known as rectangular distribution. Like all probability distributions for continuous random variables, the area under the graph of a random variable is always equal to 1.

The distribultion is defined by two parameters a and b.

where a is the minimum and b is the maximum.

The probability density function looks like the following:

An example of uniform distribution could be to find the probability that a person gains weight between 10 and 15 pounds given that the average amount of weight gained by a person over the winter months is uniformly distributed from 0 to 30lbs.

Any real life example can be related to uniform distributions as they are relatively simpler than other distributions and then probabilities and expected values or variances can be calculated
