2 Balls & 4 Boxes problem
$begingroup$
There are two balls in 4 boxes $A$, $B$, $C$ and $D$ in a table, one red and another is blue. In a box there could be one, two or no balls. Box $D$ has fallen off from the table, and there were no ball inside it. If the probability of $A$ having only the blue ball inside it can be written as $frac{p}{q}$ where $p$ and $q$ are co-prime positive integers. $p+q=?$
