A certain underlying state graph is a tree where each node has three successor nodes, indexed $a$, $b$, $c$. There are two assets defined on this tree which pay no dividends except at the terminal time $T$. At a certain period it is known that the prices of the two accets are multiplied by factors, depending on the successor node. These factors are shown in the table below:
