Understanding Sets and Venn Diagrams

The video tutorial explains how to solve a problem involving sets using a Venn diagram. It introduces the universal set S and its subsets A and B, detailing their cardinalities. The tutorial guides viewers through calculating the number of elements in A but not B by determining the intersection of A and B. It uses set notation and a formula to find the solution, concluding that there are 22 elements in A but not in B.

What is the total number of elements in the universal set S?

• 68

• 34

• 90

• 117
