The value of the z is −2.1 then the probability P(z < −2.1) is 0.0179. Then the correct option is A.

<h3>What is a normal distribution?</h3>

It is also called the Gaussian Distribution. It is the most important continuous probability distribution. The curve looks like a bell, so it is also called a bell curve.

The z-score is a numerical measurement used in statistics of the value's relationship to the mean of a group of values, measured in terms of standards from the mean.

If the value of the z is −2.1. Then the probability will be

P(z < −2.1) = 0.0179.

More about the normal distribution link is given below.
