Answer 1

Step-by-step explanation:

A = { 1, 2, 3, 4,.......}

B = { 2, 4, 6, 8,......}

C = { 1, 3, 5, 7,.......}

D = { 2, 3, 5, 7,......}

i ) A റ B = { 1, 2, 3...} റ { 2, 4, 6,...}

= { 2, 4, 6, 8,.....}

= B

ii) A റ C = { 1, 2, 3,....} റ { 1, 3, 5, 7,....}

= { 1, 3, 5, 7,.....}

= C

iii) A റ D = { 1, 2, 3 ... } റ { 2, 3, 5, 7....}.

= { 2, 3, 5, 7....}

= D

iv) B റ C = { 2, 4, 6,....} റ { 1, 3, 5, .... }

= { } = Null set

v) B റ D = { 2, 4, 6,.....} റ { 2, 3, 5, 7,.... }

= { 2 }

vi) C റ D = { 1, 3, 5,.... } റ { 2, 3, 5, 7.... }

= { 3, 5, 7, 11, 13, 17, 19,.....}

= {x : x is odd prime number }

FOR YOUR INFO : Odd prime number = 3, 5, 7, 9, .......

Even prime number= 2, 3, 5, 7, .....
