In these models, every individual tile has the same chance of being drawn. The probability of a shape is its tile count divided by the total number of tiles, not by the number of shape names. A chance between zero and one is not a promise. Zero matching tiles makes an event impossible; all matching tiles makes it certain. Each question starts with its own stated bag.
Worked example
A separate example bag holds 2 stars and 3 circles. It contains 5 tiles, so the star chance is 2/5 and the circle chance is 3/5. Circles are more likely, but a star is still possible. There are two shape names, but their chances are not both 1/2.
