I have a decision theory problem:

There are 2 courses available to take in a department. The probabilities to get scores A, B or C are :

Course P(A) P(B) P(C)

X 0.1 0.7 0.2

Y 0.3 0.4 0.3

Where the next values has to be achieved:

A: 4 points

B: 3 points

C: 2 points

To gradute you need at least a B

To get and award you need at most A, but not C

Your choices are : take X, Y or both

What is the optimal decision if you want to graduate?

What is the optimal strategy if you want to get an award?

thanks
