Question Analysis
This question involves analyzing a Venn Diagram to calculate the probability of a single event.
The main focus is on identifying the region in the Venn Diagram that represents students who like only comedy movies and then calculating the probability based on the number of students in that region and the total number of students.

Key Concept Explanation
The probability of a single event is calculated as the number of outcomes for that event divided by the total number of possible outcomes.
In the Venn Diagram, the “only C” region represents the favorable outcomes for this event.
The total number of outcomes is the sum of all the numbers in the Venn Diagram.

Step - by - Step Solution
