You are driving a bus. At the first stop, you pick up 29 people. On your second stop, 18 of those 29 people get off. What is the driver's name? A train and a bus arrive at the station at random between 9 AM and 10 AM. The train stops for 10 minutes, and the bus stops for x minutes. How can I find x so that the probability that the bus and the train will meet equals 0.5?
