( A ) is a set having ( 6 ) distinct elements. The number of distinct functions from ( A ) to ( A ) which are notbijections is

Options

  1. A( 6 !-6 )
  2. B( 6⁶-6 )
  3. C( 6⁶-6 ! )
  4. D6!

Correct answer

C. ( 6⁶-6 ! )

Step-by-step solution

Number of distinct elements are ( 6 ) So, number of distinct functions ( (A A) ) which are not bijections is Total ( - ) Bijections ( =6⁶-6 ! )
