Chapter 7.1, Problem 35E
roulette, a wheel with 38 numbers is spun. Of these. 18 are red. and 18 are black. The other two numbers, which are neither black nor red, are 0 and 00, The probabilit}' that when the wheel is spun it lands on any particular number is 1/38.
- Mat is the probabilit)' that the wheel lands on a red number?
- Mat is the probabilit}' that the wheel lands on a black number twice in a row?
- Mat is the probabilit}' that the wheel lands on 0 or 00?
- Mat is the probabilit}' that in five spins the wheel never lands on either 0 or 00?
- Mat is the probabilit)' 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?
