Question

of A={x/x=n, nen and 3 <n <8}
B={x/x=P, PEW and P<5} then find (AUB ) -( A intersection B) ​

Answer 1

Answer:

( AUB ) - ( A n B ) = { 0,1,2,3,5,6,7 }

Step-by-step explanation:

A = { x/x = n , n€N and 3 < n < 8 }

i) A = { 4,5,6,7 }

B = { x/x = P , P€W and P<5 }

ii ) B = { 0,1,2,3,4 }

iii ) A U B = { 4,5,6,7 } U { 0,1,2,3,4 }

= { 0,1,2,3,4,5,6,7}

iv ) A n B = { 4,5,6,7 } n { 0,1,2,3,4 }

= { 4 }

v ) ( AUB ) - ( A n B )

= { 0,1,2,3,4,5,6,7} - { 4 }

= { 0,1,2,3,5,6,7 }
