Question

Using the property of sets prove that C-B is a subset of C-A, if A is a subset of B

Answer 1

Step-by-step explanation:

Sure I will answer it for you mate,

let us take an example

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

A is subset of B

(C - B) = (4) , (C - A) = (3,4)

so, (C - B) is a subset of (C - A)

......Hence proved.
