Read whether each stated drawn tile is returned or kept out. Count only the remaining tiles for the next probability. If the bag still contains tiles but none match, that result has chance zero. If there are no tiles left, there is no next draw: do not invent a probability with denominator zero. Each question starts from its own stated bag.
Worked example
A separate bag has 2 stars and 1 circle. Keep both stars out: the remaining circle makes the next star chance 0/1 = 0. Keep that final circle out too and the bag is empty. Now drawing any tile is unavailable; 0/0 is not a probability.
