- 3 things to know
- Unit A2 1
Overview
Final step in calculating expected value at a chance node and formula for calculating net gain in decision tree analysis.
What you need to know
Answer each one before you reveal it.
Find the net gain on an expected value of 330,000 less a cost of 170,000, and which way do you work at each stage?

Questions from this subtopic
Each one with the model answer underneath.
- 1
What does a square symbol represent in a decision tree?
Model answer
A decision node, which represents a point where a choice must be made between alternative courses of action.
- 2
What does a circle symbol represent in a decision tree?
Model answer
A chance node, which represents a point where different outcomes may occur, each with an associated probability.
- 3
What must the probabilities at each chance node sum to?
Model answer
1 (or 100%).
- 4
When calculating expected value at a chance node, what must first be identified?
Model answer
Each possible outcome and its financial value.
- 5
After identifying outcomes and their values, what is the next step in calculating expected value?
Model answer
Multiply each outcome value by its probability.
- 6
