A certain roller coaster has 3 cars, and a passenger is equally likely to ride in any 1 of the
3 cars each time that passenger rides the roller coaster. If a certain passenger is to ride
the roller coaster 3 times, what is the probability that the passenger will ride in each of
the 3 cars?
Probab to ride in any of the cars: 1/3.
Cars: A, B, C.
Number of possible rides: number of combinations of A, B, C where no letter (car) is repeated = 3! = 6.
Total number of possible rides = 3x3x3 = 27.
Probab = 6/27.
