One six sided fair die is rolled, and one two sided fair coin is tossed. If the coin turns up heads, then the number of spots showing on the die is the value score for that trial> If the coin turns up tails, then twice the number of spots showing on the die is the value score for that trial. Determine the oucomes in the sample space, and construct a probability distribution table. Find the expected value of the following game. If I were to invited you to play a game where I would pay you your score in dollars, what should I charge you to play? Using your ticket price, how many games would have to be played in order for me to have an expected profit of $100?
