Answer:

1/(6^3)

Step-by-step explanation:

Each roll of the die constitutes a separate event.

These three events are independent.

The probability of rolling a 2 on the first throw is 1/6, since there is only one '2' among the six numbers on the die.

Because each roll is independent of the others, the probability of rolling a

2                                                              1

on all three rolls is (1/6)(1/6)(1/6), or -----------

                                                              6^3
