    If we start with 74,000 gallons and need to have at least 20,000 gallons after 11 weeks, then we cannot afford to lose more than (74,000 - 20,000)/11 each week.

    We also know that if we sell on average 50,000 gallons each week and add a constant 47,000 gallons each week, then on average we can expect to lose 3,000 gallons each week.

    Now knowing that on average we will lose 3,000 gallons each week, what is the probability we will lose more than (74,000-20,000)/11 each week?
