The next bit does not seem to have any use in this question:

The available decisions are: take X only, take Y only, take both.Where the next values has to be achieved:

A: 4 points

B: 3 points

C: 2 points

As far as I can see decision 3 dominates the others, so irrespective

of what the precise numbers are the optimal strategy is to take both.

RonLTo 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
