 In this session, we will discuss the following question and the question says, let A is equal to the set containing the elements A, B, C, D, E and B is equal to the set containing the elements 1, 2, 3, 4, 5, show A, B, A union B and A intersection B by WEND diagram. Let's start the solution now. We are given in the question that A is equal to the set containing the letters A, B, C, D, E and B is equal to the set containing the numbers 1, 2, 3, 4, 5. We will draw WEND diagram for A. First we will draw a circle which represents the set A and write down the elements of the set A inside the circle. So we write the elements A, B, C, D, E inside the circle A. So this is our WEND diagram for the set A. Now we draw the WEND diagram for B. We draw a circle which represents the set B and write down the elements of the set B that is 1, 2, 3, 4, 5 inside the circle. So this is the WEND diagram for the set B. Now we will find what is A union B. We know that the set A union B contains elements which are in the set A or in B or both. So A union B is equal to the set containing the elements A, B, C, D, E, 1, 2, 3, 4, 5. We now draw WEND diagram for A union B. First we draw two non-intersecting circles A and B which represent the two sets A and B respectively. Next we will draw the elements of the set A that is A, B, C, D, E inside the circle A and the elements of the set B inside the circle B that is we write 1, 2, 3, 4, 5 inside this circle B. Now A union B contains elements which are in A or in B or both. So this shaded region is A union B. We now write down what we have represented. A union B is represented by the shaded portion. Now we find what is A intersection B. We know that the set A intersection B contains elements which are in both A and B. Since the sets A and B are disjoint sets so they have no element in common, hence A intersection B is the null set. That is A intersection B is equal to the empty set 5. We will now draw the WEND diagram for A intersection B. As done earlier, we draw two non-intersecting circles which represent the sets A and B. Then we write down the elements of the set A inside the circle A and the elements of set B inside the circle B. Since A and B are disjoint sets so A intersection B is the empty set and is represented by this WEND diagram. With this we end our session. Hope you enjoyed the session.
