In roulette, a wheel with 38 numbers is spun. Of these, 18 are red, 18 are black, and 2 are green. The probability that when the wheel is spun it lands on any particular number is 1/38.
a) What is the probability that the wheel lands on a red number?
b) What is the probability that the wheel lands on a black number twice in a row?
c) What is the probability that the wheel lands on 0 or 00?
d) What is the probability that in five spins the wheel never lands on either 0 or 00?
e) What is the probability that the wheel lands on one of the first six integers on one spin, but does not land on any of them on the next spin?
I need to find how how to find the answers?
