Discrete Mathematics Level pending

\(20\) identical candies are to be distributed among \(20\) children.

The probability that exactly \(2\) children get no candies is of the form \(\dfrac{A}{B}\), where \(A\) and \(B\) are co-prime positive integers.

Find the digit sum of \(A+B\).


  • Any number of candies from those available can be given to any child.
