Train X and Y arrive at a station at random between 8 am to 8.20 am trains stop 4 min assuming that the trains arrive independently.
1. Determine the probability the train X.
2. Determine the probability the train meet at the station.
3. Assuming that the trains meet; Determine the probability the trains arrive.

Determine the probability that the train does what? Arrive at the station at a specific time?

In other words that one arrives within four minutes of the other.

?? You are given that the trains arrive! That probability is 1. That the trains arrive when?
