Let A={x : x is a natural number}, B ={x : x is an even natural number}
C={x : x is an odd natural number and D={x : x is a prime number}
Find `A cap B, A cap C, A cap D, B cap C, B cap D and C cap D`.

Answer

`A cap B=` {even natural number} {2,4,6.......}
`A cap C`= {odd natural numbers}
`A cap D={4,6,8,12,....10}`
`B cap C=phi`
`B cap D=` {even natural number}
`C cap D`={3,5,7,11,....}
