Answer 2

Concept

The normal distribution is a symmetrical continuous probability distribution on both sides of the mean, meaning that the right side of the centre is the mirror image of the left side. The whole area under the normal distribution curve equals one.

Given

Whole normal curve

Find

We are asked to find the area under the whole normal curve

Solution

The entire area beneath the normal curve is one. A normal random variable X has a 0% chance of equaling any value. The area under the normal curve limited by a and plus infinity is equal to the probability that X is bigger than a.

Hence the area under the whole normal curve is​ one.
