ou have noticed some variation in the amount of rice provided in your usual order of General so's Chicken. You ask the store manager about this issue and they confirm that the reparation of your order isn't directly measured. In each order, you are supposed to be given cup of rice, which should be 250 grams if measured exactly. Based on data provided by the manager, you find that the true amount of rice given follows a normal distribution with an verage of 252 grams and a standard deviation of 1.5 grams. Given this information: a) How often will you receive less rice than you pay for? (less than 250 grams) b) If your rice container can only fit 256 grams, how often will it overflow when your cook is filling it? c) If both these situations are considered as errors, how many errors should you expect after ordering 10 times?
