4.33: Variance of Random Variables | 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 4.32 to find the variance and standard deviation by using the joint probability function.
4.33 Use Definition 4.3 on page 120 to find the variance of the random variable X of Exercise 4.7 on page 117.

Sir Please make videos on Chapter No 5 "Some Discrete Probability Distributions".

[@EngineeringTutorOfficial]

Yes sure sir

@@EngineeringTutorOfficial sir chapter 5 ki Jo probability distributions hain in per aik video bana dain jis main un ka concept clear ho jay. Thank you sir

[@EngineeringTutorOfficial]

Sure sir, very soon
