You roll a fair dice. What is the probability that you will attain a five?

Answer 1

Pr(5) = 1/6

Unless by "dice" you meant two of them. (die is the singular of dice)

then there's 4 ways to get a sum of 5 out of 36 possible outcomes

1 and 4

4 and 1

2 and 3

3 and 2

Pr(5 with 2 dice) = 4/36= 1/9
