A sales office of Helms, Inc., has developed the following probability distribution for daily sales of a perishable product.
The product is restocked at the start of each day. If the company desires a 90% service level in satisfying sales demand, the initial stock balance for each day should be:Solution:The probability of demand being greater than 200 units is 10%. Therefore, the probability that sales will be 200 units or less is 90% (100% − 10%). The 90% probability for sales of 200 or less units could also be determined by adding the individual probabilities for sale of 200 units or less (0.2 + 0.5 + 0.2).Appreciate, If someone can help me to understand the concept, please?
