A 6-sided die is rolled. Find $\mathrm{P}(3$ or 5$)$. A. $\frac{1}{6}$ B. $\frac{1}{36}$ c. 2 D. $\frac{1}{3}$

Step 1 ：The question is asking for the probability of rolling a 3 or 5 on a 6-sided die.

Step 2 ：Since there are 6 possible outcomes (1, 2, 3, 4, 5, 6) and 2 of them are favorable (3, 5), the probability is \(\frac{2}{6}\) or \(\frac{1}{3}\).

Step 3 ：Final Answer: The probability of rolling a 3 or 5 on a 6-sided die is \(\boxed{\frac{1}{3}}\).
