In roulette, a wheel is divided up into slots of equal area. each slot is labeled with one of the numbers from 0 through 36, and one slot is labeled with a 00. half the slots are red, and half the slots are black. when the wheel is spun, it lands on one of these slots.( the problem is complete.) (a) if the wheel is spun three times, find the probability it lands on a 17 twice, and then a red slot.(b) if the wheel is spun three times, find the probability it does not land on the 00 slot all 3 times.(c) if the wheel is spun three times, find the probability it lands on a slot other than 00 all three times.
