Expected value of random variables - On average, how many points do you expect to receive in each round of this game?
Suppose you have 2 fair dice, one is red and the other is blue, and both have numbers 1 through 6 on their faces. You play a game in which you toss both dice, then the number of points you win is given by raising the result of the blue die to the power 2 and multiplying it by 8; while the number of points you lose is given by raising the result of the red die to the power 2 and multiplying it by 9. On average, how many points do you expect to receive in each round of this game?
Please offer the steps and an explanation of the steps in your response. Thank you!
