The correct choice for generating a random number between 0 and 79 is indeed based on how the random number is calculated and the range it covers.

In the chosen code snippet, the expression (int) Math.random() * 80 is used. The Math.random() method generates a double value between 0.0 and 1.0 (exclusive of 1.0). By multiplying this value by 80, the range of possible outcomes becomes 0.0 to 80.0, but since we convert it to an integer using (int), any decimal points are truncated, resulting in values from 0 to 79.

The truncation means that the maximum value of 80.0 does not get included in the final integer results, as it would be truncated to 80, which is outside the desired range. Therefore, the generated integers are indeed from 0 to 79, satisfying the requirement for the range specified in the question.

In contrast, other code snippets either introduce incorrect calculations, where the intended range is not achieved or result in invalid operations, thus not yielding the correct random range that is asked for.
