Question

If A = {x:x is a natural number} B={x:x
is an odd natural numbers, c{x:x is a prime numbers}, find AΠB,AΠC,AΠD,BΠC,BΠD,CΠD​

Answer 1

Step-by-step explanation:

given that:- A = ( 1,2,3,4,5,6.........)

B = ( 1,3,5,6......)

C = (2,3,5,7,11....) and D = ( )

AnB = ( 1, 3,5...)

OR

AnB = (x:x is an odd natural numbers)

AnC =( 2,3,5,7,11.....)

OR

AnC = ( x:x is a prime numbers)

AnD = ( )

BnC = ( 3,5,7 ....)

OR

BnC = ( x:x is odd prime numbers)

BnD= ( )

CnD = ( )

dear , you did not write the element of D

so,i let D as a null set .

hope it help you

Answer 2

Answer:

mark me as brainliest and support me to give more valuable answers.

Explanation:

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}
