Student Demographics and Probabilities

The video tutorial explains how to calculate probabilities using a dataset of student grades and gender. It covers the process of determining the probability of selecting a male or female student, as well as the probability of students receiving specific grades. The tutorial also demonstrates how to simplify fractions and use a TI-84 calculator for this purpose.
