Question Analysis
This question involves updating the frequency of a value after modifying the dataset (removing one occurrence).
The main focus is on understanding how removing a value affects its frequency.

Key Concept Explanation
Frequency After Removal: Removing one occurrence of a value decreases its frequency by 1. The new frequency is the original frequency minus 1 (if at least one occurrence remains).

Step-by-Step Solution
Find the original frequency of 5: In the dataset, 5 appears 3 times.
Remove one 5, so the new count is 3 - 1 = 2.
Verify with the modified dataset: 2, 2, 3, 5, 5, 7, 7—...
