Final answer:
The probability of rolling a 4 on a fair six-sided die is 1/6.
Step-by-step explanation:
To find the probability of rolling a 4 on a fair six-sided die, we need to determine the number of favorable outcomes (rolling a 4) and the total number of possible outcomes. The number of favorable outcomes is 1 (since there is only one face with a 4), and the total number of possible outcomes is 6 (since there are 6 faces on the die). Therefore, the probability of rolling a 4 is 1/6.
