Solution

///*picture in very hard to read although I`m giving this answer, if there is any fault, fell free to comment below*///

A and B arrives at 1.00 2.00 3.00 with probability 1/3

to find the probability that the A arrives 60 mins before B

that is

P( A arrives 60 mins before B)

= P( A arrives 1.00 and B arrives 2.00 ) + P( A arrives 2.00 and B arrives 3.00 )

=(1/3)*(1/3)+(1/3)*(1/3)

=2/9
