The number of tickets issued by a meter reader for parking- meter violations can be modeled by a Poisson distribution with a rate parameter of six tickets per hour. What is the probability that at least three tickets are given out during a particular hour? How many tickets do you expect to be given during a 20-min period?

**Poisson Distribution in Parking Meter Violations** The number of tickets issued by a meter reader for parking-meter violations can be modeled by a Poisson distribution with a rate parameter of six tickets per hour. **Problem 1: Probability Calculation** - **Question:** What is the probability that at least three tickets are given out during a particular hour? - **Solution Box:** (Insert your solution here) **Problem 2: Expected Tickets Calculation** - **Question:** How many tickets do you expect to be given during a 20-minute period? - **Solution Box:** (Insert your solution here) In the Poisson distribution context, the key element is the "rate parameter" which tells us the average number of occurrences (tickets in this case) in a fixed interval (one hour). - For problem 1, you would calculate the cumulative probability of fewer than three tickets and subtract from 1. - For problem 2, convert the hourly rate to a 20-minute period by adjusting the rate parameter accordingly. Understanding these problems helps in learning the application of Poisson distribution in real-world scenarios.
