Solution to belief


I am confused why the top left node has numerator (9/10x1/9) instead of (1/10x1/9) since this should be the probability of reaching this node given the strategies? Same with upper right node, why is not 1/10x8/9?

It is likely that there is a typo in the Figure; if Nature goes way $S$ with probabilty $1/10$ the calculations and results are consistent.

Hard to validate since original text of the problem or reference to where it can be found is not given.
