A standard fair six-sided die has faces numbered 1 to 6. What is the probability of rolling a 7 with this die? Enter the probability as a decimal.

Explication

The die carries only the numbers 1 to 6, so no face can show a 7 and the event never occurs, which places it at the very bottom of the probability scale, at 0. Treating 7 as one more possible result and answering one sixth invents a face the die does not have, since probability is counted among the outcomes that actually exist.
