5.A student rolls a number cube whose six faces are numbered 1 through 6.

What is the sample space for this experiment?

A.S = {1, 2, 3, 4, 5, 6}

B.S = {1, 2, 3, 4}

C.S = {2, 4, 6}

D.S = {6}

Answer 1

5/27 in simplest form because 20 flights out of 108 are linger than three hours, 20/108 (simplified is 5/27).

Answer 2

1. 5/27 in simplest form because 20 flights out of 108 are linger than three hours, 20/108 (simplified is 5/27).
2. 5/9 in simplified terms. Unsimplified is 20/36 because the dice has 6 sides, I believe the probability should be out of 36.
