Question

A cube numbered from 1 through 6 is rolled 400 times. The probability of 3 landing face-up on the cube is 1/6. Select two values that indicate an approximate relative frequency of 3 landing face-up in 400 attempts.

Answer 1

You would expect to have about 66 or 67 rolls of 3 when you rolled the die 400 times.

If you multiply the probability of a three (1/6) by the total of 400, you get about 66.67 times. Therefore, you would expect to get about 66 or 67 total rolls.
