1. In the casino game of roulette, a ball is rolled around the rim of a circular bowl while a wheel containing 38 slots into which the ball can drop is spun in the opposite direction from the rolling ball; 18 of the slots are red, 18 are black, and 2 are green. A player pays $1 to play, and wins $2 if the ball falls into the color slot the player has wagered on. Assume a player decides to bet that the ball will fall into one of the red slots. a. What is the expected return on a single bet of $1 on red

Sagot :

Answer:

0.474

Explanation:

Number of slots in the wheel = 38

Number of red slots = 18

Number of black slots = 18

Number of green slots = 2

The player decides to bet the ball will fall into one of the red slots.

The player has decides that the ball will fall into one of the red slots. Thus the probability that the player will win is [tex]$\frac{18}{38}$[/tex]

Therefore, [tex]$=\frac{18}{38}$[/tex]
