Question 903463: Roulette wheels in Las Vegas have 38 pockets. They are all numbered 0, 00, and 1 through 36. Of all 38 pockets, there are 18 red, 18 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.
A) If you spin the wheel twice, what is the probability that the ball lands in a black pocket in both spins?
Do I set problem "A" as 18/32? Which the answer would be... 0.5625, rounded to three decimals, which is 0.563. I am having trouble because of "twice" listed in problem A. I know my answer is incorrect. :(
D) If you spin the wheel twice, what is the probability that the ball lands in a same color pocket in both spins?
I have trouble setting this up because I am confused with "same color pocket."

THANK YOU IN ADVANCE.

A) P = %2818%2F38%29%2818%2F38%29
D) P = +%2818%2F38%29%2818%2F38%29+%2B+%2818%2F38%29%2818%2F38%29+%2B+%282%2F38%29%282%2F38%29
