Currently Playing: 4.34, 4.35: Variance of Random Variables | Exercise Solution of Probability & Statistics by Walpole

This is the exercise problems solution of the 9th edition of"Probability and Statistics for Engineers and Scientists by Walpole". In this video, I solve exercise problems 4.34 and 4.35 to find the variance and standard deviation by using the joint probability function. 4.34: Let X be a random variable with the following probability distribution: x −23 5 f(x) 0.3 0.2 0.5 Find the standard deviation of X. 4.35: The random variable X, representing the number of errors per 100 lines of software code, has the following probability distribution: x 2 3 45 6 f(x) 0.01 0.25 0.4 0.3 0.04 Using Theorem 4.2 on page 121, find the variance of X.
