Expert Solution
Step 1: Introduction

Random variables are of 2 types, discrete and continuous. The expected value of the random variable is the same as the mean. The formula to calculate the expectation for a continuous random variable is given below.

Standard deviation is always the square root of the variance. The variance can be calculated using the following relation.
