Hi guys

.

So I've been working on this problem for a while now I thought I had it but My lecturer said Nope. And there was a simpler way involving a graph.

ANY help would make you so utterly loved and grant you supernatural powers.

QUESTION: wo people A and B will be arriving at a small coffee bar at any time between 8am

and 9am equally likely. Each of them will stay exactly 10 minutes in the bar. What

is the probability that they will meet each other in the bar? (Hint: Let (X, Y ) be the

arrival times (in minutes) of A and B, and let M be the event that they will meet each

other. Then plot the sample space S and the event M, from which try to find the

probability of M.)
