Understand the definition of a discrete random variable: it is a variable that can take on a countable number of distinct values, often integers, such as counts of occurrences.
Analyze each option to determine if the variable is discrete or continuous:
1. The time it takes for a computer to complete a calculation is typically measured on a continuous scale (e.g., seconds, milliseconds), so it is a continuous random variable.
2. The weight of a randomly chosen apple can take any value within a range and is measured continuously, so it is a continuous random variable.
3. The number of heads obtained when flipping a coin three times can only be 0, 1, 2, or 3, which are countable values, making it a discrete random variable.
