Question

Given the sets A = {1, 2, 3}, B = {3, 4}, C = {4, 5, 6} then A U (B upside down u C) is .......... /

Answer 1

Answer:

{1,2,3,4}

Step-by-step explanation:

A={1,2,3}, B={3,4}, C={4,5,6}

then,

A∪(B∩C): A∪({3,4}∩{4,5,6})

               = {1,2,3}∪{4}

               ={1,2,3,4}

plz make my ans the brainliest, thanks

Answer 2

$\huge{\underline{\sf{\red{Answer}}}}$

A U (B ∩ C) = {1,2,3,4}

_______________________________

$\huge{\underline{\green{\tt{Given}}}}$

• A={1,2,3}

• B={3,4}

• C={4,5,6}

________________________

★ U = Union = addition of elements to set

★ ∩ = Intersection= Only common elements are taken from both

_______________________________

$\huge{\underline{\underline{\tt{SoluTion}}}}$

$\huge\implies$(B ∩ C) = { 4 }

$\huge\implies\boxed{A U (B ∩ C)= {1,2,3,4}}$
