Question

Martha rolls a 6 sided number cube (number one through six) two times. What is the probability she will roll a 3 both times?

Answer 1

2/12

Explanation:

since there are six sides, rolling twice will give you a total of 12 possibilities, each time, you have 1 chance out of 6 each time to roll 3

1/6 + 1/6 = 2/12

If you want to, or need to reduce 2/12, divide both the numerator and denominator by two, and you will get 1/6 again.
