In the game of roulette, a player can place a $10 bet on the number 13 and have a probability of winning. If the metal ball lands on 13, the player gets to keep the 38 $10 paid to play the game and the player is awarded an additional $350. Otherwise, the player is awarded nothing and the casino takes the player's $10. Find the expected value E(x) to the player for one play of the game. If x is the gain to a player in a game of chance, then E(x) is usually negative. This value gives the average amount per game the player can expect to lose.
