When you roll two number cubes, what are the odds, in simplest form, in favor of getting two number less than 4 ?

First, it depends on the answer.  If you are on the same quiz, the options should be

A) 1:3

B) 3:1

C) 1:4

D) 4:1

The answer is C or 1:4.  

Because it is in it's favor, the "1" would go first, standing as the numbers before "4" on a cube.  The probability in fraction form would be 3/6, or simplified to 1/2.  P ( >3, > 3) = P ( >3) = 1/2 x 1/2 = 1/4.  This leaves 1:4 being you're answer.
