Question

If U = {1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12); A=
(2.7, 9, 10) B = {5, 9, 10, 12) and C= {1,4,5,
7, 11). Find
1.A'
2.B'
3. A'-C
4. (B - A)'
5. B' intersection c'
6. (A U B)'
7. A' intersection B' (1 score each)​

Answer 1

Answer:

1):A complement:{1,3,4,5,6,8,11,12}

2):B complement:{1,2,3,4,6,7,8,11}

3):A complement -C =

A complement={1,3,4,5,6,8,11,12}-1,4,5,7,11

so ans.=3,6,8,12

4):B-A={2,7}

5):B complement intersection C complement=

{1,2,3,4,6,7,8,11} intersection {2,3,6,8,9,10,12}={2,3,6,7,8,}

6):(A union B) complement ={2,5,7, 9,10,12} complemnet ={1,3,4,6,8, 11}

A complemnet intersection B complemnet= {1,3,4,6, 8,11}
