This document discusses probability concepts through examples involving dice rolls. It presents three probability questions: 1) finding the probability of rolling a sum greater than 9 on two dice, 2) finding the probability of rolling a sum that is a multiple of 3, and 3) finding the probability of rolling a sum that is divisible by 3 or 4. It defines the sample space of all possible dice roll outcomes. It then calculates the probabilities for each question by determining the number of favorable outcomes and dividing by the total number of outcomes. The probabilities calculated are 1/6, 1/3, and 5/9 respectively. Students are instructed to solve similar probability problems involving dice rolls.
