In the game of roulette, a player can place a $9 bet on the number 29 and have a \( \frac{1}{38} \) probability of winning. If the metal ball lands on 29, the player gets to keep the $9 paid to play the game and the player is awarded an additional $315. Otherwise, the player is awarded nothing and the casino takes the player's $9. 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.

The expected value is $ ___ .5
