Data from the pastshows that on average, a ready-mixed concrete plant receives 100orders for concrete every year. The maximum number of orders thatthe plant can fulfil each week is 2. (a) What isthe probability that in a given week the plant cannot fulfil allthe placed orders? (b) Assume the answer to part(a) is 20% (It is not; I just want to make sure that everybody usesthe same number for part (b)). Suppose there are 5 of such plants.What is the probability that in a given week 2 of the plants cannotfulfill their orders?
