In summary, the question is asking for the probability of two people meeting in a bar for exactly 15 minutes between 12:00 and 13:00, assuming uniform arrival times. The problem has been discussed on Math Stack Exchange, where they solve it graphically and note certain restrictions, such as the arrival times being between 12:00 and 12:45. The problem may be considered ambiguous without the assumption of independent arrival times.

Two people have to spend exactly 15 consecutive minutes in a bar on a given day, between 12:00 and 13:00. Assuming uniform arrival times, what is the probability they will meet?I am mainly interested to see how people would model this formally. I came up with the answer 50% (wrong!) based on the assumptions that:- independent uniform arrival
- they will meet iff they actually overlap by some \(\displaystyle ϵ>0\)
- we can measure time continuouslybut my methods felt a little ad hoc to me, and I would like to learn to make it more formal.Also I'm curious whether people think the problem is formulated unambiguously. I added the assumption of independent arrival myself for instance, because I think without such an assumption the problem is not well defined.
