Final answer:
The probability of rolling a 1 or a 2 on a six-sided die is 1/3.
Step-by-step explanation:
To find the probability of rolling a 1 or a 2 on a six-sided die, we need to determine the number of favorable outcomes and the total number of possible outcomes. There are 2 favorable outcomes, which are rolling a 1 or a 2. The total number of possible outcomes is 6, as there are 6 sides on the die. Therefore, the probability of rolling a 1 or a 2 is 2/6, or 1/3.
