Math 104:01, Fall 2017 4. Recall from the videos In a certain die-rolling game, each time you play you roll a pair of fair dice, and if the sum equals &,you Assignment 6B win. We found that on a single roll of the dice, there is a , probability of having the sum equals. If you play the game 3 times, what is your expected number of wins? (Hint: You can think in terms of an ideal data set for the experiment of playing 3 times, but here it is easier to work with the weighted average approach to computing expected value. If you know another method for solving this problem from another course, besides what we have learned in this course, please do not use it!]Explanation / Answer
Expected no of wins = n * P
= 3 * 5/36 = 5/12 = 0.4167
