So to begin for this problem, we have that the optimal decision, or the optimal decision strategy, is going to be the decision which gives the maximum outcome, the maximum payout, for each state of nature.
00:31
So that's why for part a, you were marked correct.
00:34
For s1, we would want to go with decision 1, with a payout of 300.
00:40
For state two, we would want to go with either.
00:44
Either way, the decision or the payout would be 175.
00:50
And for state three, we would go with decision two, yielding a payout of 100.
01:01
So, as i said, looks like you have part a correct, as well as parts c and d marked correct, but it looks like you were incorrect on part b.
01:10
So to find the expected value of the decision strategy, developed in part a...
