Answer:
Explanation:
A standard number cube (also known as a dice) has six sides with each side numbered 1, 2, 3, 4, 5, or 6. Rolling a 3 or 5 is considered a favorable outcome.
There are two favorable outcomes (rolling a 3 or 5) out of six possible outcomes (rolling any number from 1 to 6).
Therefore, the probability of rolling a 3 or 5 on a number cube can be calculated as:
Probability = Number of favorable outcomes / Total number of possible outcomes
Probability = 2 / 6
Probability = 1 / 3
So the probability of rolling a 3 or 5 on a number cube is 1/3 or approximately 0.33 (33%).
