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 4.55 to find the expected value of profit from the expenditures and gained amounts by using the probability density function for discrete probability functions. 4.55 Suppose that a grocery store purchases 5 cartons of skim milk at the wholesale price of $1.20 per carton and retails the milk at $1.65 per carton. After the expiration date, the unsold milk is removed from the shelf and the grocer receives a credit from the distributor equal to three-fourths of the wholesale price. If the probability distribution of the random variable X, the number of cartons that are sold from this lot, is x: 0, 1, 2, 3, 4, 5 f(x): 1/15, 2/15, 2/15 3/15 4/15 3/15 find the expected profit. 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 #covariance #jointprobability #covarianceofrandomvariable #distribution #meanvaluecalculation #mathematicalexpectation #expectedvalue #excpectedprofit Connect with me by subscribing to: https://www.youtube.com/channel/UCVWaC4BsaESbmijsPMe7QaA/featured Happy Learning :-)
