Question

Q2. If Set A={1,2,3,4}, Set B={2,3,4,5} and Set C={3,4,5,6} then find:
1. (A-B) UC
II. A- (B0C)
III. (A-B) U (B-C)​

Answer 1

Answer:

I){3,4,5,6}

II){1}

III){5,2}

Step-by-step explanation:

given:

A={1,2,3,4}

B={2,3,4,5}

C={3,4,5,6}

1)(A-B)UC

(A-B) ={1,2,3,4}-{2,3,4,5}

={5}

(A-B)UC={5}U{3,4,5,6}

={3,4,5,6}

_________________________________________

II)A-(BUC)

(BUC)={2,3,4,5}U{3,4,5,6}

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

A-(BUC)={1,2,3,4}-{2,3,4,5,6}

={1}

_________________________________________

III) (A-B)U(B-C)

(A-B)={5}

(B-C)={2,3,4,5}-{3,4,5,6}

={2}

(A-B)U(B-C)={5}U{2}

={5,2}
