In Fig.5, ordered pairs are _________.2. These ordered pairs constitute a _______.3. The ordered pairs (A, P), (B, R), (C, Q), (E, Q), (D, T), (G, T), (F, U), (H, U)constitute a relation which is also a _____.4. The ordered pairs (B, R), (C, Q), (D, T), (E, S), (E, Q) constitute a _____which is not a _____

The tuples of the relations can be of ________ order.

Which ordered pairs need to be added to the relationp = {(a,a),(a,d),(b,b),(b,d),(c,c),(d,a),(d,b)}on the set X = {a,b,c,d} to create the equivalence relation p* generated by p? A (a,a) B (a,b) C (a,c) D (a,d) E (b,a) F (b,b) G (b,c) H (b,d) I (c,a) J (c,b) K (c,c) L (c,d) M (d,a) N (d,b) O (d,c) P (d,d) Q None of them

The set of second components in the ordered pairs is called the range of the relation.a.Trueb.False
