Question

ifA=(1,2,3), B=(3,4,5), C=(1,3).
verify that A-(BUC)=(A-B)U(A-C)
​

Answer 1

Answer:

ur questions is wrong which is this type

A-(BUC)=(A-B) intersection(A-C)

Given,

A=(1,2,3), B=(3,4,5), C=(1,3)

then,

A-(BUC)={1,2,3}-[{3,4,5}U{1,3}]

={1,2,3}-{1,3,4}

={2}

And,

(A-B) intersection(A-C)= [{1,2,3}-{3,4,5}] intersection[{1,2,3}-{1,3}]

={1,2} intersection{2}

={2}

therefore,

A-(BUC)=(A-B) intersection(A-C)
