Steps

Step 1 :In American roulette, the croupier spins a marble that lands in one of the 38 slots in a revolving turntable. The slots are numbered 1 to 36, with two additional slots labeled 0 and 00 that are painted green.

Step 2 :Assume a single spin of the roulette wheel is made. An example of a five-number bet is betting that the marble will land in a slot numbered 10,11,12,13, or 14.

Step 3 :The total number of outcomes is the total number of slots, which is 38.

Step 4 :The number of outcomes in the event is the number of slots the player is betting on, which is 5.

Step 5 :The probability of winning is the number of outcomes in the event divided by the total number of outcomes. So, the probability is \(\frac{5}{38}\).

Step 6 :Final Answer: The probability of winning with a five-number bet in American roulette is approximately \(\boxed{0.1316}\).
