Question

Suppose u and v both have values of type set and u^v == u + v. From this we can conclude that:
1. u and v are identical
2. u and v are disjoint
3. u is a subset of v
4. v is a subset of u

Answer 1

the right answer is the no 3

Answer 2

Answer: 4. v is a subset of u.

In order to make the condition $u^v = u + v$ as TRUE and with the given condition u and v both denote sets in Python. The given statement can be set true when the set v is a subset of u.

For example,

                                        u = { 1,2,3 }

                                        v = { 1, 2 }

Then u + v = { 1,2, 3} On the other hand $u^v = {1,2}$ and this is equal to v. Hence v is the subset of u.
