Question

7. Two sets A and B are such that AB = Ø. Draw a Venn-diagram to show the relationship between A and B. Shade the regio representing : (1) AUB (ii) (A U B)' (iii) B-A (iv) BOA

​

Answer 1

Answer:

Let A=2,3,,4,5,6,7 and B=4,6,7,8,9

Then A∩B={4,6,7}

A∩B represent the numbers that are present in both sets. That is represented as the shaded region in the venn-diagram.
