roulette consists in placing a small ball in a roulette wheel, Probability (Roulette ball not landing on red) = 10 / 19

The probability of an event can be calculated by probability formula by simply dividing the favorable number of outcomes by the total number of possible outcomes

Given:

Number of total slots = 38

Number of red slots = 18

Number of black slots = 18

Number of green slots = 2

Find:

Probability (Roulette ball not landing on red)

Computation:

Probability (Roulette ball not landing on red) = 1 - Probability (Roulette ball landing on red)

Probability (Roulette ball not landing on red) = 1 - (18 / 38)

Probability (Roulette ball not landing on red) = 20 / 38

Probability (Roulette ball not landing on red) = 10 / 19
