Step-by-step explanation:
प्रश्नानुसार हल करने पर
A = { 1,2,3,4,5,.....}
B = { 2,4,6,8,........}
C = { 1,3,5,7,9,......}
D = { 2,3,5,7,11,13,......}
(i) A ∩ B = { 1,2,3,4,5,.....} ∩ { 2,4,6,8,........}
= { 2,4,6,8,......} = B
(ii) A ∩ C = { 1,2,3,4,5,.....} ∩ { 1,3,5,7,9,......}
= { 1,3,5,7 .....} = C
(iii) A ∩ D = { 1,2,3,4,5,.....} ∩ { 2,3,5,7,11,13,......}
= { 2,3,5,7,11,......} = D
(iv) B ∩ C = { 2,4,6,8...} ∩ { 1,3,5,7,....}
= ∅
(v) B ∩ D = { 2,4,6,8,........} ∩ { 2,3,5,7,11,......}
= { 2 }
(vi) C ∩ D = { 1,3,5,7,....} ∩ { 2,3,5,7,11,13.....}
= { 3,5,7,11,......}
= { x : x एक विषम अभाज्य संख्या है। }
