This math topic focuses on probability problems involving coin tosses, specifically looking at the probability of flipping at least one specific result—either heads or tails—using fraction equations. It is part of a broader unit on Probability and Counting concerning Multiple Events. The problems are structured to help students understand how to calculate probability using various combinations of outcomes from flipping two coins, and determine the correct equation that represents the scenario described. Each question offers multiple choice answers, often including expressions such as simple fractions, sums, products of probabilities, or the complement rule.
