It has two ways of getting supplies to its troops: it can send a convoy up the river road or it can send a convoy overland through the jungle.

of the supplies will get through, but 9 army soldiers will be lost. Each day a supply convoy travels one of the roads, and if the guerrillas are watching the other road, the convoy gets through with no losses. What is the
