A copy room uses a two-bin system to manage inventory of paper whereby a number of bundles of paper are placed by the copy machine (call this bin 1) and an additional 12 bundles are placed in storage (call this bin 2 ). When the bundles in bin 1 run out, an order is placed with the supplier and the 12 bundles in bin 2 are retrieved and used during the three day leadtime that they wait for the replenishment order from the supplier. If demand for paper averages 3 bundles per day with a standard deviation of 0.85, what is the probability of having enough bundles while waiting for the replenishment order
