Probability and Sock Selection

The video tutorial from YourTeacher.com explains how to calculate the probability of drawing two red socks consecutively from a drawer without replacement. It covers the concept of dependent events and demonstrates the step-by-step calculation of probabilities for each event, including simplification of fractions to find the final probability.
