प्रश्न
If A = {5, 6, 7, 8, 9}, B = {x : 3 < x < 8 and x ∈ W} and C = {x : x ≤ 5 and x ∈ N}. Find:
A ∩ B and (A ∩ B) ∩ C
उत्तर
Find A ∩ B
A ∩ B = {5, 6, 7, 8, 9} ∩ {4, 5, 6, 7}
A ∩ B = {5, 6, 7}
Find (A ∩ B) ∩ C
(A ∩ B) ∩ C = {5, 6, 7} ∩ {1, 2, 3, 4, 5}
(A ∩ B) ∩ C = {5}
- A ∩ B = {5, 6, 7}
- (A ∩ B) ∩ C = {5}
