How to solve; you roll a pair of number cubes what is the probability of rolling a number less than 4 on both cubes?

6 numbers per cube

3 numbers are less than 4 (1, 2 & 3)

so you have a 3/6, reduce to 1/2 probability of rolling a number less than 4 on each cube

2 cubes

so 1/2 * 1/2 = 1/4 probability
