## What is the probability of a rolling dice less than 5?

Hence, P(values less than 5) = 4/6 = **2/3**. To find the complement of rolling a number less than 5, we use the formula P’ = 1 – P, where P’ is the complement of P. = 1/3. Hence, the probability of the complement of rolling a number less than 5 by using a six-sided die is 1/3.

## What is the probability of getting a sum of 5 when you roll 2 dice?
