Question

When you roll two number cubes, what are the odds, in simplest form, in favor of getting two numbers less than 3?

A. 1:8
B. 8:1
C. 1:9
D. 9:1

Answer 1

A

Explanation:

The successful results are

1 1

2 1

1 2

2 2

So the formula is probability of winning to probability of losing

Probability of winning =

4/36 = 0.1111111

Probability of losing =

32/36 = 0.88888888

So the odds are expressed as 0.111111 / 0.88888 = 1 in 8
