If the outcome of the roll (the number of dots on the side facing upward) is odd, you win as many dollars as the number you have rolled. Otherwise, you lose as many dollars as the number you have rolled. Let X be the profit of the game or the amount of money won or lost per roll. Negative profit corresponds to lost money. (a) What is your profit of the outcome if the roll is 6? 24 (b) Fill out the following probability distribution table. (Round your answers to two decimal places). Outcome Probability (c) Compute the expected value (the mean) of X. (Round your answer to the nearest hundredth.) (d) Explain the meaning of the expected value of X in the context of this problem.
