1. Suppose the color that comes out for the first time is X, and the color that comes out for the second time happens to be Y, then in any case, the color that comes out for the third time is either X or Y, so it is impossible to have the third situation (according to the meaning of the question, there is no third color). So when the third candy came out, mom happened to have 1 pairs of candy of the same color.

2. Suppose the color that comes out for the first time is X, and the color that comes out for the second time is X ... and then mom happens to have 1 pairs of candy with the same color.
