A person has to go both Northwards & Southwards in search of a job. He decides to go by the first train he encounters.There are trains for every 15 min both southwards and northwards. First train towards south is at 6:00 A.M. and that towards North is at 6:10. If the person arrives at any random time, what is the probability that he gets into a train towards North

• In a frequency of 15 mins if the person comes in first 10 mins he will catch northwards train. so the probability that he gets into a train towards North is 10/15=0.66
  If he comes in the next 5 mins he will catch southwards train.so the probability of getting into a train towards southwards is 5/15=0.33

• 2/5...
  for south time he had is 15 min.
  for north time he had is 6:25-6:15=10 min.
  pro for north is 10/15+10=2/5

• My answer is 0.5 as out of total of 8 samples (time duration between the timings i.e. 6:00 -6:10 , 6:10-6:15 and so on) favorable are 4 i.e. for north(6:00-6:10,6:15-6:25 and so on)
