A Correct answer
Explanation

The die has 6 faces in total. The number 2 appears on 3 of those faces. Therefore, the probability is 3/6, which simplifies to 1/2.

AI explanation

Using the classical probability formula, the probability equals the number of favorable faces divided by the total number of faces. The die has three faces marked with the number 2 out of a total of 6 faces. Therefore, the required probability is 3/6, which simplifies to 1/2.
