This problem is in a multiple choice question and the teacher gave us the answer but he didn't explain how. Can anyone show me the steps?
This is the problem:
Consider a Poisson process with a rate of 18 events per hour. What is the
probability that the 10th event occurs not later than 20 minutes after the
eighth?
The answer is 0.983
Poisson process is memoryless, so it is simply asking the chances of at least 2 events in a 20 minute period. Can you take it from there?
