Question

Roulette is a game of chance that involves spinning a wheel that is divided into 38 equal segments, as shown in the accompanying picture.

An image of a roulette wheel is shown. Text to the side of the image reads "©Anna Baburkina/Shutterstock.com."

A metal ball is tossed into the wheel as it is spinning, and the ball eventually lands in one of the 38 segments. Each segment has an associated color. Two segments are green. Half of the other 36 segments are red and the others are black. When a balanced roulette wheel is spun, the ball is equally likely to land in any one of the 38 segments.

PART A)When a balanced roulette wheel is spun, what is the probability that the ball lands in a green segment? (Round your answer to three decimal places.)

PART C) Suppose that you watch 1000 spins of a roulette wheel and note the color that results from each spin. What would be an indication that the wheel was not balanced? (Select all that apply.)

If the number of spins that landed on green was much less than the answer from part (a) times 1000.

need help with part C please

If the number of spins that landed on green was much greater than the answer from part (a) times 1000.

If the number of spins that landed on green was approximately equal to the answer from part (a) times 1000.

Answer 1

A balanced roulette wheel 2 segments green, 18 red and 18 black.

A)The probability that the ball lands in a green segment is .

C) In 1000 spins of a fair roulette wheel , we shoud get approximately,

green, red and black each. If the roulette wheel is not balanced, the results will deviate from these values significantly.

The correct choices are the first 2 choices.

If the number of spins that landed on green was much less than the answer from part (a) times 1000.

If the number of spins that landed on green was much greater than the answer from part (a) times 1000.
