Video Summary

At a party with 12 children, including 3 pairs of twins, hats are distributed where twins wear hats of the same color. There are two cases: <br /><br />1. All twins have the same color hats (either all red or all blue), leaving 6 ways for others, totaling 2 ways.<br />2. Not all twins have the same color (2 pairs share one color, and 1 pair the other). There are 6 configuration options for twins, and 15 ways for others, totaling 90 ways.<br /><br />Adding both cases gives a total of 92 distribution ways. Therefore, the answer is 92.
