What is the probability of getting an even number when rolling a six-sided number cube?

A. 0.5
B. 5%
C. StartFraction 2 over 6 EndFraction
D. 30%.

C. 2/6, which simplifies to 1/3 or approximately 33.3%. There are three even numbers on a six-sided number cube: 2, 4, and 6. Out of a total of six possible outcomes, the probability of rolling an even number is 3/6, which reduces to 1/2 or 0.5.

To find the probability of getting an even number when rolling a six-sided number cube, we need to determine the number of favorable outcomes (even numbers) and the total number of possible outcomes.

The favorable outcomes in this case are numbers 2, 4, and 6, which are all even. So, there are 3 favorable outcomes.

The total number of possible outcomes when rolling a six-sided number cube is 6, since there are 6 numbers (1, 2, 3, 4, 5, 6).

Therefore, the probability of getting an even number can be calculated as the ratio of favorable outcomes to total outcomes:

Probability = Favorable outcomes / Total outcomes = 3 / 6 = 1 / 2

So, the correct answer is C. StartFraction 2 over 6 EndFraction
