 Hello and welcome to the session. In this session we will discuss the following question and the question says, let O is equal to the set containing the elements 1, 2, 3, 4, 5, 6, 7, 8, 9. B, the universal set A is equal to the set containing the elements 1, 2, B is equal to the set containing the elements 6, 7, 8. Illustrate this information on a WEM diagram. Let's start the solution now. First step is draw a rectangle which represents the universal set O. So, we have drawn this rectangle and this rectangle represents the universal set O. The second step is draw two non-intersecting circles representing the sets A and B. So, we have drawn these two circles which represent the sets A and B. We can see that the sets A and B have no common elements. So, they are disjoint sets. Hence, these two circles are non-intersecting. The third step is write down the elements of the sets A and B inside the circles A and B respectively. So, we write down the elements of A that is 1, 2 and 3 inside this circle and the elements of B that is 6, 7, 8 inside this circle. So, we write down the elements of the set O which are not in A or B outside the two circles but inside the rectangle. Now, the remaining elements of the set O which are not in the sets A or B are 5, 4 and 9. So, we write down these elements in the region outside these two circles but inside the rectangle. So, we write down the elements 5, 4 and 9 in this portion outside the circles. So, this is the Venn diagram for this question where the sets A and B are represented by the circles A and B respectively and the universal set O is represented by this rectangle. With this, we end our session. Hope you enjoyed the session.
