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?
Total outcome = 3*3*3 as the person can ride any of the three cars. Favorable outcome = 3*2*1 (as the first time, the person can ride any of the three cars, second time, only the remaining two cars and third time only remaining one car).
