Question

IfA={3,4,5,6,7,8,9} & B= {6,7,8,9} then
find AUB & ANB.​

Answer 1

Answer:

AUB

{3,4,5,6,7,8,9}

ANB

{6,7,8,9}

Answer 2

Answer:

Step-by-step explanation:

A={3,4,5,6,7,8,9}

B={6,7,8,9}

now,

∴A n B={6,7,8,9}

AUB=n(A)+n(B)-n(A n B)

={3,4,5,6,7,8,9}+{6,7,8,9}-{6,7,8,9}

∴n(AUB)={3,4,5}
