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 customer is to ride the roller coaster 3 times, what is the probability that the customer will ride in each of the 3 cars?

I think the prob is (3*2*1)/(3*3*3)=6/27=22.22%
