- the probability of the event to happen before the D day is x/(x+y+1);
- the probability of the event to happen on the D day is 1/(x+y+1);
- the probability of the event to happen after the D day is y/(x+y+1).

If my assumption that the daily probabilities are not even is false, then the computation is more complex given how we compute the daily probabilities.
That made my brain hurt...
