Question

HOMEWORK: If A= {letters of the word B= { letters of the word

ENGLISH }

SINGING}

FIND, A unionB and A intersection B.

If P={ factors of 6}

Q={ factors of 8} Find Punion Q and P intersection Q.​

Answer 1

Step-by-step explanation:

1) Given :-

A= {letters of the word ENGLISH }

B= { letters of the word SINGING}

To find:-

Find, A unionB and A intersection B.

Solution:-

Given that

A= {letters of the word ENGLISH }

A ={ E,N,G,L,I,S,H}

B= { letters of the word SINGING}

B={S,I,N,G}

AUB = { E,N,G,L,I,S,H} U {S,I,N,G}

AUB ={E,N,G,L,I,S,H}

AnB= { E,N,G,L,I,S,H} n {S,I,N,G}

AnB = { S,I,N,G}

Answer:-

AUB = { E,N,G,L,I,S,H} U {S,I,N,G}

AUB = A

AnB= { E,N,G,L,I,S,H} n {S,I,N,G}

AnB = B

2) Given:-

P={ factors of 6}

Q={ factors of 8}

To find:-

Find P union Q and P intersection Q.

Solution:-

Given that

P={ factors of 6}

P = {1,2,3,6}

Q={ factors of 8}

Q = {1,2,4,8}

PUQ={1,2,3,6} U{1,2,4,8}

PUQ ={1,2,3,4,6,8}

PnQ = {1,2,3,6} n{1,2,4,8}

PnQ = {1,2}
