Module 12 Lesson 2 - Probability and Counting

Front

What is the intersection of two sets A and B?

Back

The intersection of two sets A and B, denoted as A ∩ B, is the set of elements that are common to both A and B.

Front

If A = {1, 2, 3, 4, 5, 6} and B = {1, 2, 3, 5, 7, 9}, what is A U B?

Back

A U B = {1, 2, 3, 4, 5, 6, 7, 9}. The union of two sets A and B includes all elements from both sets without duplicates.

Front

What does the symbol '∪' represent in set theory?

Back

The symbol '∪' represents the union of two sets, meaning it combines all elements from both sets.

Front

What does the symbol '∩' represent in set theory?

Back

The symbol '∩' represents the intersection of two sets, meaning it includes only the elements that are present in both sets.

Front

What is the complement of a set A, denoted as A'?

Back

The complement of a set A, denoted as A', includes all elements that are not in set A.

Front

If A = {1, 2, 3} and B = {3, 4, 5}, what is A ∩ B?

Back

A ∩ B = {3}. It includes only the elements that are common to both sets.

Front

If A = {1, 2, 3} and B = {2, 3, 4}, what is A U B?

Back

A U B = {1, 2, 3, 4}. It combines all unique elements from both sets.

Front

What does the shaded region in a Venn diagram typically represent?

Back

The shaded region in a Venn diagram represents the union, intersection, or complement of sets, depending on the context.

Front

What is the difference between union and intersection?

Back

Union combines all elements from both sets, while intersection includes only the elements that are common to both sets.

Front

If A = {x | x is an even number} and B = {x | x is a prime number}, what is A ∩ B?

Back

A ∩ B = {2}. It includes only the even prime number.
