. In the casino game roulette, a wheel with 38 spaces (18 red, 18 black, and 2 green) is spun. In one possible bet, the player bets $1 on a single number. If that number is spun on the wheel, then they receive $36 (their original $1 $35). Otherwise, they lose their $1. On average, how much money should a player expect to win or lose if they play this game repeatedly

Respuesta :

Answer:

For each game, the player should be expected to lose $0.0263.

Step-by-step explanation:

A probability is the number of desired outcomes divided by the number of total outcomes.

Probability of each outcome:

1/38 probability of winning, that is, 1/38 probability of receiving $36.

37/38 probability of losing, that is, 37/38 probability of losing $1.

On average, how much money should a player expect to win or lose if they play this game repeatedly?

For each game:

[tex]E(X) = \frac{1}{38}*36 - \frac{37}{38}*1 = \frac{36 - 37}{38} = -\frac{1}{38} = -0.0263[/tex]

For each game, the player should be expected to lose $0.0263.
