Every mоrning, wоrkers аt а phаrmaceutical manufacturing facility fill up water cоntainers for the water they may have to use that day in the process. Each time they fill up water containers, they have to test the water to ensure it complies with FDA testing requirements. This testing costs $40. The water itself costs $0.10 per gallon. The required usage of water follows a normal distribution with a mean of 500 gallons and a standard deviation of 25 gallons. If the workers get too much water at the beginning of the day, the excess is poured down the drain since it cannot be used the following day. This disposal comes at no cost. If the amount the water the workers get at the beginning of the day is not enough, they have to go get the exact amount of water still needed. To refill the containers, they have to first complete the testing requirements again, incurring the cost of $40 again (in addition to the $0.10 per gallon). Using the influence diagram attached, build a spreadsheet to answer the next several questions. INFLUENCE DIAGRAM What is the probability of needing to fill the water containers a second time if they get 530 gallons at the beginning of the day?
