Question

You would have probably seen a roulette wheel in a casino. The wheel contains 38 slots, each containing a number from 1 to 36. The remaining two slots contain the numbers 0 and 00. The wheel is spun, and a white-colored ball rolls over it, having an equal probability of landing at any of the 38 slots. When the ball lands on a number, it determines the outcome of the game.

Options:
a. The wheel contains 37 slots, each numbered from 0 to 36.
b. The wheel contains 36 slots, each numbered from 1 to 36.
c. The wheel contains 39 slots, each numbered from 1 to 37.
d. The wheel contains 40 slots, each numbered from 0 to 39.

Answer 1

The student's question deals with the probability of a roulette wheel landing on a certain number, using the knowledge that a typical American roulette wheel contains 38 equally probable slots. The question illustrates basic probability principles within mathematics, focusing on the equal likelihood of events and the long-term relative frequency of outcomes in gambling scenarios.

Step-by-step explanation:

The question provided involves probability and understanding the composition of a roulette wheel which is a concept in mathematics, particularly focusing on probability and statistics. A typical American roulette wheel contains 38 slots; numbers 1 to 36, and the two additional slots for 0 and 00. The question describes a scenario with a roulette wheel, and you are to calculate or understand the probabilities associated with different outcomes of spinning this wheel.

For instance, if we were to calculate the probability of the ball landing on any specific number, we would use the fact that each of the 38 slots has an equal probability. Thus, the probability of landing on a specific number would be 1 out of 38, or approximately 2.63%.

In addition, when considering long-term relative frequency, as the number of spins increases, the actual results should get closer to the theoretical probability. This concept is essential when considering gambling outcomes and helps understand why casinos can predict their earnings over time.
