The thickness is a uniform random variable with values between 150 and 200 millimeters. Any sheets less than 160 millimeters thick must be scrapped because they are unacceptable to the buyers. The following figure displays the uniform distribution for this example. Figure 2 Note that for continuous distribution, probability is calculated by finding the area under the function over a specific interval. In other words, for continuous distributions, there is no probability at any one point.
Normal distribution is probably one of the most important and widely used continuous distribution.
It is known as a normal random variable, and its probability distribution is called a normal distribution. It is asymptotic to the axis, i.e., it extends indefinitely in either direction from the mean. It is a continuous distribution. It is a family of curves, i.e., every unique pair of mean and standard deviation defines a different normal distribution. See the following figure.
