25. The number of oil tankers arriving at a port
between successive high tides has a Poisson
distribution with mean 2. The depth of the water
is such that loaded vessels can enter the dock
area only on the high tide. The port has dock
space for only three tankers, which are
discharged and leave the dock area before the
next tide. Only the first three loaded tankers
waiting at any high tide go into the dock area;
any others must await another high tide.
Starting from an evening high tide after which no
ships remain waiting their turn, find (to three
decimal places) the probabilities that after the
next morning's high tide
(a) the three dock berths remain empty,
(b) the three berths are all filled.
Find (to two decimal places) the probability that
no tankers are left waiting outside the dock area
after the following evening's high tide. (NEAB)
