Q. Is equal set an equivalent set?
Equal sets are equivalent, but equivalent sets may not be equal. Two sets are equal when they have exactly the same elements, and sets are equivalent when a one-to-one correspondence can be set up between the two sets.
Q. What is the definition of universal set?
A universal set is the collection of all objects in a particular context or theory. All other sets in that framework constitute subsets of the universal set, which is denoted as an uppercase italic letter U. The objects themselves are known as elements or members of U.

Q. What is two set equality?
more Sets that have precisely the same elements. They don’t have to be in the same order. Example: {1,2,3,4} and {3,4,2,1} are equal.
Q. Are equal sets equivalent sets what about the converse?
All equal sets are equivalent since both the sets have same number of elements. But the converse need not be true since they may not have same elements. For example : A={1,2,3,4,5} and B={7,8,9,10,11} are equivalents sets, since n(A)=n(B).
Q. How do you know if sets are equivalent?
Equivalent sets have different elements but have the same amount of elements. If we want to write that two sets are equivalent, we would use the tilde (~) sign. A set’s cardinality is the number of elements in the set. Therefore, if two sets have the same cardinality, they are equivalent!
Q. What is the law of set?
Set Operations and the Laws of Set Theory. • The union of sets A and B is the set A ∪ B = {x : x ∈ A ∨ x ∈ B}. • The intersection of sets A and B is the set A ∩ B = {x : x ∈ A ∧ x ∈ B}.
Q. What is set Difference law?
Set Difference: The relative complement or set difference of sets A and B, denoted A – B, is the set of all elements in A that are not in B. Then the set difference of A and B would be the $407 remaining in the checking account. Example: Let A = {a, b, c, d} and B = {b, d, e}. Then A – B = {a, c} and B – A = {e}.
