Given the word problem, we can deduce the following information:
1. A single die is rolled.
To determine the probability of rolling a number less than 6 using a single die, we note first that a single die can give us six values: 1,2,3,4,5,6.
There are 5 numbers that are less than 6 so the probability of rolling a number less than 6 is 5/6.
Therefore, the answer is 5/6.
