Suppose you set up a carnival booth game at a local fund-raising event. The game consists of rolling a giant six-sided die. The participants pay $3 per roll. A participant who rolls a 6 wins a prize that costs you $8. A participant who rolls a 1 wins a prize that costs you $2.50. Participants who roll other numbers win nothing.  You will have to find out the expected value of your gain by answering several questions below.    

Find the expected gain from one game (the expected value, mean, of X). Round your answer to two decimal places.

Let X be your gain after one game. Complete the probability table below. That is find the following probabilities: P(rolling 6)  P(rolling 1)  P(rolling a number other than 6 or 1) Probability table Rolls Your gain, X P(X) 6  -$5 (participant pays $3 to play and wins. You pay $8) 1 $0.50 (participant pays $3 to play and wins. You pay $2.50) A number other than 1 or 6 $3 (participant pays $3 to play and lose)
