A bag of cookies is underweight if it weighs less than 500 grams. The filling process dispenses cookies with weight that follows the normal distribution with mean 510 grams and standard deviation 4 grams. If you randomly select 5 bags, what is the probability that exactly 2 of them will be underweight?
