Using a venn diagram to determine the theoretical probability

The video tutorial explains how to calculate the theoretical probability of a student studying Spanish but not French from a group of 195 students. It uses Venn diagrams to visualize the problem, calculates the number of students studying each language, and determines the probability. The tutorial verifies the result by comparing it to a logical estimate.

How many students are not taking either Spanish or French?

Explain how the Venn diagram helps in understanding the distribution of students studying Spanish and French.
