What is the minimum number of elements in a reflexive relation defined on the set A = {a,c,d}
How many elements are there in the reflexive relation defined on the set A = {1}?
How many of the following statements are wrong
1. A relation is said to be reflexive on set A if each element in A is related to itself.
2. Empty relation defined on a non- empty set is reflexive
3. We can define a reflexive relation on A x B, where A is not a subset of B.
4. In a reflexive relation, all the elements should be of the form (a,a) for all a from the set on which the relation is defined
What is the minimum number of elements an equivalence relation defined on the set A {1,2,3} would have?
Universal relation defined on a set A is reflexive.
