Question

what is the probability of the ball landing on a red slot in american roulette?
a. 18/37
b. 18/36
c. 18/38
d. 1/2

Explanation:

Step1: Determine the total number of slots

In American roulette, there are \(38\) slots (\(18\) red, \(18\) black, and \(2\) green ( \(0\) and \(00\))).

Step2: Use the probability formula

The probability formula is \(P=\frac{\text{Number of favorable outcomes}}{\text{Total number of outcomes}}\). Here, the number of favorable outcomes (red slots) is \(18\), and the total number of outcomes is \(38\). So \(P = \frac{18}{38}\)

Answer:

C. \(18/38\)
