The graph shows the weights (in kilograms) of different fish caught during a fishing competition. Is the variable in the graph discrete or continuous? Explain your reasoning.

• A. It is a discrete random variable because each fish is unique
• B. It is a continuous random variable because the number of fish caught can only be measured in whole numbers
• C. It is a discrete random variable because weight is counted in specific intervals
• D. It is a continuous random variable because weight can take on any value within a given range, including decimals

Answer: (D)
