Write two sets A and B such that A⊆Band B⊆A. State the relationship between sets A and B.
Let A = {letters of TALE}
B = {Letters of LATE}
Here A⊆B, and B⊆A
∴ A = B
If A and B are two sets such that A⊂B, then write B' - A' in terms of A and B.
Two sets A and B are such that A ∩B=ϕ. Draw a venn-diagram to show the relationship between A and B. Shade the region representing :
(i) A ∪ B
(ii) (A ∪ B)'
(iii) B - A
(iv) B ∩ A'
If A and B are two sets such that n (A) = 20, n(B) = 25 and n(A∪B)= 40, then write n(A∩B).
