Example: Hamburger patties are packed 8 to a box, and each box is supposed to have 1 Kg of meat in it. The weights of the patties vary a little because they are mass produced, and the weight X of a single patty is actually a random variable with mean μ = 0.128 kg and standard deviation o = 0.005 kg. Find the probability a box has at least 1 kg of meat, assuming that the weights of the 8 patties in any given box are independent.
