Video Summary

The problem involves identifying the missing letter on a ball in a triangular pyramid made of 10 balls, each marked with letters A, B, C, D, and E, with two balls per letter. By analyzing the given side views and noting the overlapping sections, duplicates can be crossed out to manage the letter distribution. After eliminating duplicates through the process, all letters have their required pair except for the letter A, which appears only once. Therefore, the missing ball with the question mark must be an A to complete the set of two for each letter.
