Question

if A=1,2,3number of reflective relations of`A' is​

Answer 1

Answer:

Given, A=a,b,c

Here, the number of elements in set A is 3.

We know that, if set A has n elements, then total number of reflexive relations is 2  

n  2  −n .  

Here, n=3

Therefore, the total number of reflexive relations from set A to A  

=2^3²-2  

=2^ 6  =64.
