The optimal order quantity is determined by the critical ratio, which is the ratio of the cost of underage to the sum of the cost of underage and overage. The critical ratio here is (6-3)/(6-3+3-1) = 0.6. The cumulative probability that meets or exceeds this ratio is 0.2 + 0.3 + 0.4 = 0.9, which corresponds to ordering 7 units.
