Atrain arrives at a station and waits 2 min before departing. another train arrives at the station 18 minutes later, repeating the cycle. identify the probability that a train will be at the station when you arrive. !

If the second train arrives at the station 18 minutes after the first one DEPARTS, then there's a train waiting at the station for 2 minutes out of every 20.

So the probability a train will be there when you arrive is

2/20 = 0.1

36/60

36/2=18

60/2=30

18/30

18/3=6

30/3=10

6/10

6/2=3

10/2=5

your final answer would be 3/5 of an

hope this !

i’m sorry but i don’t know sorry
