Calculate release utility in the default case.
0.9*10+0.1*(-50)=4 utility units.
What first-outcome probability ties review under the default utilities?
60p-50=2, so p=52/60, approximately 0.8667.
Why does the transfer case not have a unique utility winner?
Retry and escalation both have expected utility 1; input order resolves the computational tie, not the valuation.
