A small grocery store realizes that they can model the number of people in the store using a Poisson distribution, with mean 6. What is the chance that 6 people will be in the store at any given time? (round, if necessary, to the nearest 10th of a percent)
1-50%
2-44.6%
3-16.1%
4-55.4%
I wouldn't have thought you'd be given a specific question about the Poisson distribution on an exam unless you had studied that distribution in class.
