Question

Robert will roll a number cube, labeled 1 through 6, a total of 200 times. About how many times could Robert expect to roll a number greater than 4?

Answer 1

Robert can expect to roll a number greater than 4 about 67 out of 200 times.

Explanation:

The number cube consists of 6 sides-- 6 outcomes. A number greater than 4 would be either 5 or 6-- two of the 6 outcomes. Knowing this, we can multiply the total times it is rolled by 2/6 (number of successful outcomes) to get our answer.

200 x 2/6 = 66.67
