 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, be the universal set and A is equal to the set containing the elements 1, 2, 4, illustrate this information on a Venn diagram. Let's start the solution now. We are given that O which is equal to the set containing the elements 1, 2, 3, 4, 5, 6 is the universal set and A which is equal to the set containing the elements 1, 2, 4. We have to draw a Venn diagram for these two sets. So the first step is draw a rectangle which represents the universal set O. So we have drawn this rectangle and it represents the universal set O. Now the second step is draw a circle inside the rectangle which represents the set A. So we have drawn this circle inside the rectangle and this circle represents the set A. The third step is write down the elements of set A inside the circle. The elements of the set A are 1, 2 and 4. So we write down these elements inside the circle. The fourth step is write down the remaining elements of the set O which are not in A outside the circle but inside the rectangle. We can see that the remaining elements of the set O which are not in set A that is elements other than the elements 1, 2 and 4 are 3, 5 and 6. So we write down these remaining elements in this portion outside the circle but inside this rectangle. So this is the Venn diagram for this question where set O which is the universal set is represented by this rectangle and set A is represented by this circle. Elements of set A are written inside this circle and the elements of set O are written inside this rectangle including the elements of set A. With this we end our session. Hope you enjoyed the session.
