Question

let A ={1,2,3,4,5},B={4,5,6,7,8}and C={7,8,9,10,11} then A∩(B∪C) is


{1,2,3,4,5,7,8}

{4,5}

{1,2,3,4,5}

{6,7,8,9,10,11}​

Answer 1

Answer:

Let's first find :- (B U C) = {4,5,6,7,8,9,10,11}

Now, A N ( B U C) = {1, 2,3,4,5} N { 4,5,6,7,8,9,10,11}

= {4,5}

Answer 2

Step-by-step explanation:

A = { 1,2,3,4,5 }

B = { 4,5,6,7,8 }

C = { 7,8,9,10,11 }

then,

A∩(B∪C) is,

{1,2,3,4,5 } ∩ { (4,5,6,7,8) U (7,8,9,10,11) }

= {1,2,3,4,5} ∩ {4,5,6,7,8,9,10,11}

={4,5}
