Step 1

Normal distribution:

A continuous random variable X is said to follow normal distribution with mean (m) and standard deviation (σ) if the probability density function of X is,

Step 2

Standard normal distribution:

The standard normal distribution is a special case of normal distribution. The standard normal distribution will have mean 0 and standard deviation 1. If a random variable X follows normal distribution with mean (m) and standard deviation (σ), then the standard normal variable z will be as given below:

Step 3

An important property of the normal distribution:

The normal distribution is symmetric. Thus, for any pai...
