I don't teach much in person any more. I am so bad-looking that there were complaints from students. When I did teach at the Richmond campus I often got coffee before class at the Tim's there.

Just for fun I wanted to find the probability of getting coffee in less than 2 minutes. I measured average wait times at the Tim's and found two minutes and seven seconds, with a standard deviation of 21 seconds. The times were normally distributed. Find the probability of me getting my coffee in less than two minutes. Round down to three decimal places. Answer as a probability.
