Probability Concepts and Card Games

The video tutorial explains how to calculate the probability of drawing two hearts from a standard deck of 52 cards. It covers two methods: using combinations and considering dependent events without replacement. The tutorial provides a step-by-step guide on using a calculator to compute combinations and verifies the results using both methods, arriving at a probability of approximately 5.88%.
