Question

In the game of​ roulette, a player can place a ​$6 bet on the number 25 and have a 1/38 probability of winning. If the metal ball lands on 25​, 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. What is the expected value of the game to the​ player? If you played the game 1000​ times, how much would you expect to​ lose?

Answer 1

AS THE WINNING PROBABILITY IS 1/38 WHICH MEANS AFTER PLAYING 38 GAMES U WILL WIL ONE GAME

COST OF 38 GAMES = 38*6 = 228

WINNING AMOUNT = 210 +6 = 216

HENCE LOSS IN 38 GAMES = 228 -216= 12

LOSS PER GAME = 12/38 = 0.316

HENCE E(X) = - 0.316

B) IF THE GAME IS PLAYED 1000 TIMES THEN TO TOTAL LOSS

AS LOSS PER GAME 0.316

HENCE LOSS AFTER 1000 TIMES = 0.316 *1000 = 316
