B Correct answer
Explanation

A die has 6 faces. The probability of rolling a 4 is 1/6. The probability of rolling a 6 is 1/6. Total probability = 1/6 + 1/6 = 2/6 = 1/3.

AI explanation

An unbiased cubical die has 6 equally likely outcomes, and the favorable outcomes for getting a 4 or a 6 are exactly two. Using the classical probability formula, the probability is 2 divided by 6, which simplifies to 1/3.
