1. Determining the Poisson Distribution
The number of meteors that hit the earth in a given day is modelled by a Poisson Distribution with $\lambda=4$. What is the probability that 5 meteors hit the earth in a day?
1. When making a video I typically make 1 error for every 20 minutes of video time. If I make 45 minutes of video what is the probability that I make 3 errors?
1. In a particular community the average person survives to age 100 with probability 0.005 (which is equivalent to 0.5%). If this community has 2,000 people, then what is the probability that 15 people in this community survive to age 100 using;
1. The Binomial Distribution
2. The Poisson Distribution
On U.S. route 66 (an American highway) every car that travels this whole route has a probability of $p=0.0002$ of getting into a car accident. A total of 10,000 cars drive this route every month. What is the probability that there are fewer than 3 car accidents in a month?
