Answer:
Explanation:
The probability of rolling a number less than or equal to 5 on a fair number cube (also known as a fair six-sided die) is 5/6.
Justification: A fair number cube has six sides, numbered 1 through 6. Out of these six numbers, there are five numbers (1, 2, 3, 4, and 5) that are less than or equal to 5. Therefore, the favorable outcomes are 5, and the total possible outcomes are 6. Thus, the probability is 5/6.
