Question

Answer with solution....​

Answer 1

Answer:

a) C={2,4,6,8,10}

b)I) 8

II)7

iii)1

iv)8

v) 7

vi)2

vii)2

Step-by-step explanation:

a)From Given..

If y=1 =>x=2(1)=2

If y=2 =>x=2(2)=4

If y=3 =>x=2(3)=6

If y=4 =>x=2(4)=8

If y=5 =>x=2(5)=10

So,The Elements in C={2,4,6,8,10}

b)I)n(A)=4,n(B)=4

n(A)+n(B)=4+4=8

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

AUB={9,7,5,8}U{6,5,4,3}

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

n(AUB) =7

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

AΠB={9,7,5,8}Π{6,5,4,3}

={5}

n(AΠB) =1

iv)From II) and iii)

n(AUB)+n(AΠB)=7+1=8

v)B={6,5,4,3},C={2,4,6,8,10}

BUC={6,5,4,3}U{2,4,6,8,10}

={6,5,4,3,2,8,10}

n(BUC)=7

vi)B={6,5,4,3},C={2,4,6,8,10}

BΠC={6,5,4,3}Π{2,4,6,8,10}

={6,4}

n(BΠC)=2

vii)n(B)=4,n(C)=5,n(BUC)=7

n(B)+n(C)-n(BUC)=4+5-7=9-7=2
