Math Problem Statement

List the elements of the following sets from the figure shown: U, A'∪B', A'∩B', A'∩B, A∪B', and reflect the sets A = {2, 4, 5, 8}, B = {3, 4, 6, 8}, U = {1, 2, 3, 4, 5, 6, 7, 8}.

Solution

Let's go through the image step by step and solve the problems.

Part A: Venn Diagram

1. UU (Universal Set)

The universal set UU consists of all elements inside and outside the circles, which in this case are the letters: U={a,b,c,d,e,f,g,h,i,j}U = \{a, b, c, d, e, f, g, h, i, j\}

2. ABA' \cup B'

  • AA' is the complement of set AA, meaning all elements not in AA. The elements outside AA are {d,e,f,g,h,i,j}\{d, e, f, g, h, i, j\}.
  • BB' is the complement of set BB, meaning all elements not in BB. The elements outside BB are {a,b,h,i,j}\{a, b, h, i, j\}.

The union ABA' \cup B' consists of all elements in AA' or BB': AB={a,b,d,e,f,g,h,i,j}A' \cup B' = \{a, b, d, e, f, g, h, i, j\}

3. ABA' \cap B'

The intersection ABA' \cap B' consists of elements that are both in AA' and BB'. This would be the elements outside both AA and BB, which are: AB={h,i,j}A' \cap B' = \{h, i, j\}

4. ABA' \cap B

This is the intersection of the complement of AA and set BB. So, we are looking for elements in BB that are not in AA: AB={d,f}A' \cap B = \{d, f\}

5. ABA \cup B'

This is the union of set AA and the complement of BB. The elements in AA are {a,b,c}\{a, b, c\} and the elements in BB' are {a,b,h,i,j}\{a, b, h, i, j\}. The union is: AB={a,b,c,h,i,j}A \cup B' = \{a, b, c, h, i, j\}


Part B: Given sets A={2,4,5,8}A = \{2, 4, 5, 8\}, B={3,4,6,8}B = \{3, 4, 6, 8\}, and U={1,2,3,4,5,6,7,8}U = \{1, 2, 3, 4, 5, 6, 7, 8\}

1. AA'

AA' is the complement of set AA, meaning all elements in the universal set UU that are not in AA. So: A={1,3,6,7}A' = \{1, 3, 6, 7\}


Would you like further clarification on any of these solutions? Let me know if you'd like more details or if you have any other questions.

Here are 5 related questions you can consider:

  1. What is the intersection of ABA \cap B from Part B?
  2. What is BAB' \cup A' using the sets from Part B?
  3. Can you visualize how the complement of a set affects its union or intersection?
  4. How would you solve for ABA \cap B' in Part B?
  5. How can you verify your Venn diagram answers by comparing them with the actual sets?

Tip: In Venn diagrams, intersections represent the common elements between sets, while unions gather elements from both sets.
