Solved Exercise Problems of Chapter No. 4: Probability & Statistics for Engineers and Scientists by Walpole 9th Edition

Currently Playing: 4.3: Expected Value of Random Variables | Exercise Solution of Probability & Statistics by Walpole

This is the start of a new chapter of the 9th edition of"Probability and Statistics for Engineers and Scientists by Walpole". In this video, I solve exercise problem 4.3 to find the expected value or average value of a random variable discussed in problem 3.25. 4.3 Find the mean of the random variable T representing the total of the three coins in Exercise 3.25 on page 93. Exercise 3.25: From a box containing 4 dimes and 2 nickels, 3 coins are selected at random without replacement. Find the probability distribution for the total T of the 3 coins. Express the probability distribution graphically as a probability histogram. https://youtu.be/ZdD60aDQCV8 Thank you for visiting the channel.
