WebApr 12, 2024 · Calculating the expected value of the sum of the rolls is tedious using our basic methods. Instead, we make the following argument: "Well, the expected value for each die is \(3.5\), and the two dice rolls are independent events, so the expected value for their sum should be \(3.5+3.5=7\)." And this is true—these expected values add. WebComputing Expected Value of a Game of Chance: Probabilities Must be Calculated From the Context Example.
