15.9% is its stock out probability if Store A’s order quantity is 800 units

Solution:

z-score = [tex]\frac{(Order quantity-Mean)}{Standard deviation}[/tex]

             = (800-500)/300 = 1

So , in-stock probability = NORM.S.DIST(1,TRUE) = 0.841345

Hence stock-out probability = 1 - 0.841345

                                               = 0.158655

                                               = 15.9% (Approximately)
