Draw a Venn diagram showing the elements of sets A, B, and the universe for all 4 regions.

Demonstrate DeMorgan’s Laws using a Venn diagram.

  1. Draw a Venn diagram showing the elements of sets A, B, and the universe for all 4 regions.
  2. Draw a second diagram showing only the elements of the complement of set A.
  3. Draw a third diagram showing only the elements of the complement of set B.
  4. Draw a fourth diagram showing the union of steps 2 and 3 for the first DeMorgan’s law or the intersection of steps 2 and 3 for the second DeMorgan’s law.
  5. Draw a fifth diagram showing the elements of the intersection of sets A and B for the first DeMorgan’s law or the union of sets A and B for the second DeMorgan’s law.
  6. Finally, draw the last diagram showing the complement of step 5. Compare the results from step 4 against those in step 6 to prove both DeMorgan’s laws. In the absence of data elements, you can use 4 different colors to clearly indicate the regions of the universe and follow all of the steps.
