ACT SAT Prep How to determine the probability of a situation

The video tutorial explains a probability problem where Jude has 12 shirts, 3 of which are black. The task is to find the probability of selecting a non-black shirt. The teacher emphasizes the concept of 'part over whole' in probability, where the total number of shirts is the whole, and the number of non-black shirts is the part. By subtracting the number of black shirts from the total, the teacher calculates the probability of selecting a non-black shirt as 3/4.
