Question Analysis
This question involves the concept of probability when dealing with the outcomes of a single roll of a die.
The main focus is on determining the number of favorable outcomes (rolling an even number) and the total number of possible outcomes (the six faces of the die) to calculate the probability.

Key Concept Explanation
For a fair die, each face has an equal chance of showing up when rolled.
The probability of an event is still calculated as the ratio of the number of favorable outcomes to the total number of possible outcomes.

Step-by-Step Solution
The total number of possible outcomes when rolling a six - sided die is 6 (the numbers 1, 2, 3, 4, 5, and 6).
The even numbers on a die are 2, 4, and 6, so the number of favorable outcomes is 3.
Using the probability formula P = number of favorable outcomes ...
