Question

If A={1, 2, 3, 4, 5}, B={5, 6, 7, 8} and C={1, a, b}, then find ∪ ∪ ,

∩ ∩ , − , − , and write all possible subests of C.​

Answer 1

Answer:

1. A U B= {1,2,3,4,5,6,7,8}

2.B U C={5,6,7,8,1,a,b}

3.C U A={1,2,3,4,5,a,b}

4. AΠ B={5}

5. BΠ C=Φ

6.CΠA={1}

7.A-B={1,2,3,4}

8.B-C={5,6,7,8}

9.C-A={2,3,4,5}

10.subsets of C={1},{a},{b},{1,a},{1,b},{a,b}{,1,a,b}
