2..5..23. A Coast Guard dispatcher receives an SOS from a ship that has run aground off the
shore of a small island. Before the captain can relay her exact {X)Sition, though, her radio goes dead. The dispatclle r has n helicopter crews he can send out to conduct a search. He suspects the ship is somewhere either south i n area l (with probability p) or north in area IC (with probability 1 - p ). Each of the n rescue parties is equally competent and has probability r of locating the ship given it has run aground in the sector being searched. How should !.he dispatcher deploy the heLicopter crews to maximize the probability that one of them will find the missing ship? Hint: Assume that m search crews are sent to area I a nd n m are sent to area II. Let B denote the event th.a t the ship is found, let At be the event that the sh.ip is in area I, and let Az be the event that the ship is in area IL Use Theorem 2.4.1 l o get an expression for P( B); then differentiate with respect to m.
2.S.29. A computer is instructed to generate a random sequence using the digits O through 9; repetitions are permissible. What is the shortest length the sequence can be and still have at least a 70% probability of containing at least one 4?
