In the game of roulette, a player can place a $4 bet on the number 24 and have a StartFraction 1 Over 38 EndFraction probability of winning. If the metal ball lands on 24, the player gets to keep the $4 paid to play the game and the player is awarded an additional $140. Otherwise, the player is awarded nothing and the casino takes the player's $4. 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 :
given data :-
the game of roulette, a player can place = 4 bet on the number 24
the player gets to keep the paid to play the = 4
the game and the player is awarded an additional = 140.
the game times = 1000
here,
probability of wiining =1/38 as 24 is one of slot of 38
probability of losing =37/38
therefore expected value of the game to the? player
=140(1/38)-4(37/38)
= 140*0.0263 - 4*0.973
= 3.684 - 3.892
= -0.208
expected lose for 1000 games = -1000(140(1/38)-4*(37/38))
= -1000*-0.208
= 208
the expect to lose is = $ 208
