A single, standard number cube is tossed. What is the probability of getting a number other than 6?

A. 1
B. start fraction 1 over 3 end fraction
C. start fraction 5 over 6 end fraction
D. start fraction 1 over 6 end fraction

The number cube has six equally likely outcomes, which are 1, 2, 3, 4, 5, or 6. The probability of getting a 6 is 1/6, so the probability of getting a number other than 6 is:

1 - 1/6 = 5/6

Therefore, the answer is choice C.
