Step 1 Introduction:

Probability: Probability is a chance factor that occurs at every outcome of a random experiment. Probability is defined as the ratio of number of favorable outcome to the total number of possible outcomes.

The formula for the probability is given by

p = A / S

where A is number of favorable outcome

          S is the total number of possible outcomes or it is also known as Sample Space(SS).

Standard Normal distribution: Let X be a continuous random variable of the scores for the reading portion of a test is normally​ distributed with a mean of 21.4 and a standard deviation of 6.9.

i.e., X ~ N(21.4 , 6.9)

Then the standard normal variate z = (X - μ) / σ

where μ is population mean and σ is population standard deviation.
