Step-by-step explanation:

Consider the provided set.

A = {2,3,4,7}, B = {4,6,7}, C = {3,5,7,8,9}

Where A, B, and universe of discourse

So

Part (A) Calculate AUB.

AUB represents the elements which are in A or in B or in both.

Therefore, AUB = {2,3,4,6,7}

Part (B) Find A n B

represent the elements which are in both the set A and B.

Therefore,

Part (C) Find C'

represent the elements that are not in C.

So the set C' contains all the element of set U except 3,5,7,8,9

Therefore,

Part (D) Find C-B

represent the elements of C which are not the elements of B.

So the set C-B contains all the element of set C except 7

Therefore,

Part (E) Find (BUC)'

represent all the elements of U which are not in B or in C or in both.

Therefore,

what's that
