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.

It is a discrete random variable because each fish is unique

It is a continuous random variable because the number of fish caught can only be measured in whole numbers

It is a discrete random variable because weight is counted in specific intervals

It is a continuous random variable because weight can take on any value within a given range, including decimals
