A standard fair six-sided die is rolled once. What is the probability that the result is a number less than 7?

Explication

The faces show 1, 2, 3, 4, 5 and 6, and every one of them is less than 7, so the event happens on every roll and sits at the top of the probability scale, which is 1. Writing 6 records how many faces succeed rather than a probability, and the scale never runs above 1 however many outcomes an experiment has.
