Silly Sally sells sea shells at the Sea Shore Store. The average and standard deviation of demand during replenishment lead time is 60 and 10?units, respectively. Sally sipped Sangria at the Silver Spoon Saloon and forgot to place a replenishment order. If Sally places an order at the end today when she has 65 units on hand what is the probability she? doesn’t run out of sea shells before the replenishment? arrives?
