Statistics

Roulette wheels in Nevada have 38 pockets. They are all numbered 0, 00, and 1 through 36. Of all 38 pockets, there are 18 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.

If you spin the wheel twice, what is the probability lands in a black pocket in both spins?


If you spin the wheel three times, what is the probability that the ball lands in the same pocket in all three spins?


How do I set up these problems?
