The probability of rolling a specific number on a standard six-sided die is determined by the ratio of favorable outcomes to the total number of possible outcomes.

In this scenario, when rolling a six-sided die, there are six possible outcomes: 1, 2, 3, 4, 5, and 6. The event we are interested in is rolling a 2, which represents one favorable outcome. Therefore, the probability of rolling a 2 can be calculated as follows:

The formula for probability is given by:

\[

\text{Probability} = \frac{\text{Number of favorable outcomes}}{\text{Total number of possible outcomes}}

\]

Substituting the values, we have:

\[

\text{Probability of rolling a 2} = \frac{1}{6}

\]

This indicates that there is one favorable outcome (rolling a 2) out of six possible outcomes. Hence, the correct answer reflects the precise calculation of this probability. Other choices represent probabilities that do not align with the defined context of a single event occurring on a six-sided die.
