Albertsons Bakery is trying to organize their cake baking procedure. The process begins with preheating the oven, gathering cooking utensils, gathering ingredients, greasing baking sheet, mixing ingredients, pouring ingredients into baking sheet, and baking the cake. Use both the CPM method and the PERT method to determine the total duration time. Then calculate so that the probability that the cake will be cooked faster than the original time after each crash.
