if two men were about to meet between 9a.m and 11 a.m.if one leaves the place only when the other hasnt reached dat place for more than 20 mins.the first person will leave .what is their probability of meeting?

• 19/20
  as he will leave once the time reaches 20 min...in all the other cases they will meet.
  I am not sure though.
