Question

ξ = { all digits in our number system}, A = { x | x is prime } B = { x | x is even } then B – A is

1.{4,6,8}
2.{0,4,6,8}
3.{3,5,7}
4.{2}

who will give answer i will frst give answer i will mark as brainliest​

Answer 1

A={x:xis a natural number}={1,2,3,4,5.....}

B={x:x is an even natural number}={2,4,6,8.....}

C={x:x is an odd natural number}={1,3,5,7,9.......}

D={x:xis a prime number}={2,3,5,7....}

(i) A∩B={x:x is a even natural number}=B

(ii) A∩C={x:x is an odd natural number}=C

(iii) A∩D={x:x is a prime number}=D

(iv) B∩C=ϕ

(v) B∩D={2}

(vi) C∩D={x:xis odd prime number}
