Understanding Sets and Venn Diagrams

The video tutorial explains the concept of universal sets and subsets, focusing on sets A and B. It covers the cardinality of these sets and their union, using a Venn diagram to illustrate the intersection. The tutorial calculates the number of elements in set B but not in set A and determines the elements in the universal set that are not in either subset. The final answer to the problem is provided, with a clear explanation of the steps involved.

How many elements are there in the universal set S?

• 35

• 127

• 93
