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.
