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 4.43 to find the mean and variance by using the joint probability function for continuous probability functions 4.43 The length of time, in minutes, for an airplane to obtain clearance for take-off at a certain airport is a random variable Y = 3X −2, where X has the density function f(x) = 1/4 e(−x/4), x greater than 0 0, elsewhere. Find the mean and variance of the random variable Y . Thank you for visiting the channel. This channel is all about the latest trends and concepts related to the problems a student encounter while studying Electrical and Computer Engineering. We are specialized in covering the material related to Electrical and Electronics Circuit Analysis, Artificial Intelligence, Probability and Statistics, Data Science, Machine Learning, and Deep Learning, to name a few. #basicprobability #probabilityandstatistics #randomvariables #variance #standarddeviation #walpole #probabilitydistributions #problemsolutions #meanvaluecalculation #mathematicalexpectation #expectedvalue Connect with me by subscribing to: https://www.youtube.com/channel/UCVWaC4BsaESbmijsPMe7QaA/featured Happy Learning :-)
