The image presents a probability distribution of a random variable that represents the number of extracurricular activities a college freshman participates in. Below is the tabulated data:| $ x $ | $ P(x) $ ||---|---|| 0 | 0.06 || 1 | 0.13 || 2 | 0.45 || 3 | 0.21 || 4 | 0.15 |In this distribution:- $ x $ represents the number of extracurricular activities.- $ P(x) $ is the probability of a freshman participating in $ x $ activities.Additionally, there is a button labeled "Send data to Excel" suggesting that the data can be exported for further analysis. **Part 3 of 3**(c) Find the probability that a student participates in at least one activity.The probability that a student participates in at least one activity is [ ].

High school students in Michigan sometimes get "snow days" in the winter when the roads are so bad that school is canceled for the day. Define the random variableX = the number of snow days at a certain high school in Michigan for a randomly selected school year. Suppose the table below gives the probability distribution of X. 1. Value x, 1. 3 4 5 6 7 8 9 10 Probability p, ? 0.19 0.14 0.10 0.07 0.05 0.04 0.04 0.02 0.01 0.01 (a) Write the event “the school year has O snow days" in terms of X. Then find its probability. (b) At this high school, if more than 5 snow days are used over the course of the year, students are required to make up the time at the end of the school year. What's the probability that a randomly selected school year will require make-up days?
