38. Suppose the number of different accounts the family members have at a bank is given by the following probability distribution: 32% of the families have 1 account; 29% of the families have 2 accounts; 12% of the families have 3 accounts; and the remaining families have 4 accounts. What is the expected number of accounts of a randomly chosen family? (please round your answer to 1 decimal place)

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?
