Question

A=(11,12,13)B=(3,14,15)verify n(AUB) =n(A) +n(B) - n(AnB)

Answer 1

Answer:

A={11,12,13}, B={3,14,15}

n(AUB)={11,12,13,3,14,15}=6

n(A)=3

n(B)=3

n(AnB)={}=0

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

6=3+3-0

6=6

Hence verified.......

Step-by-step explanation:

Hope it helps......

Answer 2

Answer:

let try

Step-by-step explanation:

n(AUB)=(11,12,13,3,14,15)=6

n(A)=3,n(B)=3,n(AnB)=0

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

6=3+3-0

6=6

verified
