A roulette wheel has 38 pockets numbered 0,00, and 1 to 36. Of all 38 pockets 18 are red, 18 are black and 2 are green. Each time the wheel is spun, a ball lands in one of the pockets, and each pocket is equally likely. Question: If you spin the wheel twice, what is the probability that the ball lands in a diffrent color pocket in both spins?

P (R) = (18/38)

P (G) = (2/38)

P (B) = (18/38)

Step-by-step explanation:

Each spin is independent of the others, so the probabilities of the three possible outcomes (R, G, B) for each spin are:

P (R) = (18/38)

P (G) = (2/38)

P (B) = (18/38)
