1. What decision would maximize the expected payoff?

2. Construct an opportunity loss table and determine the best decision by minimizing expected opportunity loss.

3. Determine the expected value with perfect information (EVWPI) and the expected value of perfect information (EVPI).

SCENARIO 2

The manager of a sports shop intends to purchase some basketballs. The demands for the basketballs are 20,30 or 40. He can either order 20,30 or 40 basketballs at RM40 each. He sells basketball for RM60. However, if these are unsold basketballs at the end of the year, the manager will return the basketballs to the supplier at RM30 each.

Construct a payoff table. Determine the number of basketballs that the manager should order according to

1. Maximax Criterion.
2. Maximin Criterion.
3. Equally likely Criterion.
