1. **Stating the problem:** We have 100 students who recorded the time taken to eat a pizza, shown by a cumulative frequency diagram. We are asked to find the probability that two randomly chosen students both took more than 45 minutes to eat the pizza. 2. **Understanding the cumulative frequency diagram:** The cumulative frequency diagram shows the total number of students who took up to a certain time to eat the pizza. The maximum cumulative frequency is 100 at the highest time. 3. **Interpreting the problem:** The problem asks for the probability that both students took more than 45 minutes. However, the time axis in the graph only goes up to about 15 minutes, so the "more than 45 minutes" likely refers to a different problem or a misinterpretation. 4. **Re-examining the problem:** The user also mentions a table about distances thrown (less than 30 m and 30 or more), which seems unrelated to the pizza eating times. 5. **Conclusion:** Since the pizza eating times do not reach 45 minutes, and the probability question is about throwing a ball more than 45 m, the relevant data is from the table about distances thrown. 6. **Using the table:** Assuming the table shows the number of students who threw less than 30 m and 30 or more, but we need the number who threw more than 45 m. Since the table only has two categories, we cannot directly find the number who threw more than 45 m. 7. **Final step:** Because the problem is incomplete or inconsistent, we cannot calculate the probability that both students threw the ball more than 45 m with the given data. **Answer:** Insufficient data to find the probability that both students threw the ball more than 45 m.
