    2/9

    Step-by-step explanation:

    certain roller coaster has 3 cars

    passenger is equally likely to ride in any 1 of the 3 cars each time that passenger rides the roller coaster.

    First time a passenger can ride any car p=3/3 = 1

    Second time the passenger should ride another car p=2/3;

    Third time the passenger should ride not the 2 cars he had already driven: p=1/3.

    so the probability that the passenger will ride in each of the 3 cars P = 1*2/3*1/3 = 2/9
