Two ships have the same berth
in a port. It is known that the
arrival times of the two ships
are independent and have the
same probability of docking
on a Sunday (00.00−24.00)
If the berth time of the first ship
is 2 hours and the berth time
of the second ship is 4 hours,
the probability that one ship
will have to wait until the
berth can be used is
□ ((67)/(144)) □ ((67)/(288)) □ (1/4) □((33)/(144))
