Question

c. rolling two standard number cubes and both cubes show a 1, 2, 3, 4, 5, or 6.

Explanation:

Step1: Determine possible outcomes for one cube

A standard number cube has 6 possible outcomes (1, 2, 3, 4, 5, 6), so the probability for one cube showing a valid number (which is always true here) is $P_1 = \frac{6}{6}=1$.

Step2: Determine probability for two cubes

Since the rolls are independent, the probability that both cubes show a valid number is the product of their individual probabilities. So $P = P_1\times P_1 = 1\times1 = 1$.

Answer:

The probability is 1.
