Decision Trees

Re Coursework 2 Please could you clarify a couple of things:
1. How many EMV figures should I end up with?

You should have an EMV for each option to enable you to compare them and make your choice.

2. How many decesion trees do I have to draw?

This has already been asked. Please see this query here.

3. There are no figures of the profits Mark will make, do I use the high and low forecasts that Yvette suggests however this does not seem to work?

Yes - use the revenues and costs given in the case to calculate the profits for each option.
