Last night, Dave and Kathy both arrived at Pizza Palace at two different random times between 10:00 p.m. and midnight. They had agreed to wait exactly 15 minutes for each other to arrive before leaving. What is the probability that Dave and Kathy were together at Pizza Palace last night between 10:00 p.m. and midnight?
I can rock the hell out of a math class, but I’m no math prodigy. Not by a long shot. After looking up the worked answer to the problem above, I wrote “holy shit” in my notes. How was I supposed to get that? I’ll write you a free blog post if you know the answer and can explain how you got it.
Update: We have a winner.
