What is the probability of rolling a number divisible by seven on a regular die?

A regular die has six faces numbered from one to six. None of these are divisible by seven, as the only numbers divisible by seven would be in the seven times table, for example, seven, 14, 21, 28, and so on.

We know that the range of values for probability go from zero to one. If an event is impossible, the probability is zero. And if it is certain, the probability is one. As it is impossible to roll a number divisible by seven on a regular dice, our answer is zero.
