Currently Playing: 4.49: Variance of Random Variable | Exercise Solution of Probability & Statistics by Walpole 9th Ed

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 problem 4.49 to find the variance and standard deviation by using the joint probability function for discrete probability functions. 4.49 Consider the situation in Exercise 4.32 on page 119. The distribution of the number of imperfections per 10 meters of synthetic failure is given by x: 0, 1, 2, 3, 4 f(x): 0.41, 0.37, 0.16, 0.05, 0.01 Find the variance and standard deviation of the number of imperfections.
