Understanding Probability Selection Criteria

The video tutorial explains how to solve an SAT math probability question. It begins by introducing the problem, which involves determining the probability of selecting a student who voted for a lion mascot from a group of 80 students. Key concepts in probability are discussed, such as identifying the pool from which selections are made. The tutorial then walks through the calculation process, showing that the probability is 1/4. The video concludes by confirming the answer as choice C.
