# For each of 5-21 prove each statement that is true and find a counterexample for each statement that is false. Assume all sets are subsets of a universal set U.For all sets A and B, if A x ⊆ B then A ∪ B = U .

To determine

To Prove:

For each prove each statement that is true and find a counterexample for each statement that is false. Assume all sets are subsets of a universal set U.

For all sets A and B,ifAcB then AB=U.

Explanation

Given information:

Let  A and B  be any set

Concept used:

:Union of sets:Intersection of sets

: subset of set

Calculation:

The objective is to prove that the provided statement is true and compute the example when the statement is false.

Consider the subsets AandB consists in a universal set U, such that is AcB
