If the metal ball lands on 13, the player gets to keep the $6 paid to play the game and the player is awarded an additional $210. Otherwise, the player is awarded nothing and the casino takes the player's $6. Find the expected value E(x) to the player for one play of the game.

average amount per game the player can expect to lose.
The expected value is $
