Minimax regret table

Minimax (regret table): Best option from Worst Outcomes [If demand is in Column; and Contract is in Rows;] Demand----Probability-------------Contract ---------------------------------300-----500------700------800 400--------------0.2--------2900----3500----4100----4400 500--------------0.3--------3400----4000----4600----4400 700--------------0.4--------4400----5000----4600----4400 900--------------0.1--------5400----5000----4600----4400 Demand---Probability-------------Contract ---------------------------------300-----500-----700-----800 400-------------0.2---------2500----1500----500-------0 500-------------0.3---------2000----1000------0--------0 700-------------0.4---------1000-------0--------0--------0 900-------------0.1------------0---------0--------0--------0 Worst Outcomes: 300 units = $2500 500 units = $1500 700 units = $500 (Best Option) 800 units = $0 Sign contract for 700 units; It doesn't matter whether we make regret table based on rows or columns (both result in the same answer).
