Let A={a , b , c) and the relation R be ...

Let `A={a , b , c)` and the relation R be defined on A as follows: `R={(a , a),(b , c),(a , b)}dot` Then, write minimum number of ordered pairs to be added in R to make it reflexive and transitive.

Text Solution

Verified by Experts

The correct Answer is:
N/a
Given relation, `R={(a,a),(b,c),(a,b)}`
To make R is reflexive we must add (b, b) and (c, c) to R. Also, to make R is transitive we must add (a,c) to R.
So, mimimum number of ordered pair is to be added are (b, b), (c, c), (a, c).
