Let X be the number of gallons of ice cream that is requested at a certain store on a hot summer day. Let us assume that the p.d.f. of X is:
f (x) = 12x (1000 – x)2/1012 for 0 < x < 1000, zero elsewhere.
How many gallons of ice cream should the store have on hand each of these days, so that the probability of exhausting its supply on a particular day is 0.05?
