A number cube with the numbers 1 through 6 is rolled. Find the probability.

P(Compliment of 4)

The compliment of 4 would be all the numbers except 4, so it would be 1, 2, 3, 5, and 6. There are five possible outcomes that are in the compliment of 4, out of a total of six possible outcomes.

Therefore, the probability of rolling a number that is in the compliment of 4 is:

P(Compliment of 4) = 5/6
