Little math problem(s) October 2020
I still have a lot to catch up, but if I guess I can add a couple of contributios even if I missed a lot in the last years.
Months ago, before Covid 19, I got in the metro. After few stations a colleague entered the train and sat directly beside me and we didn't recognize each other until we were at the station near to work. I was busy reading and he too. Then I thought: what are the odds that we sit, without noticing each other, near to each other? Given that: - train schedule is a train every 5 minutes (between stations the train use 2 minutes, when there are no problems) - period of time where we can pick the train is like 2 hours (from 7 to 9 AM) - my station is 5 or 6 stations before his (he takes sometime one, sometime the other) - we work around 275 days a year, say 240 to avoid holidays/sickness (and I do not include those times where I take the bike) - a train has 8 cars (let's assume that entering a different car means sitting away, although some trains have a lot of cars connected) - Using an average train (it depends on which type of car is used), per car there are 48 places (sitting). Wikis are great, Contribute :) |
