Consider an economy with two types of firms, S and I. S firms all move together. I firms move independently. For both types of firms, there is a

56% probability that the firm will have a 9% return and a 44% probability that the firm will have a 18% return. What is the volatility (standard deviation) of a portfolio that consists of an equal investment in:

a.36 firms of type S?

b. 36 firms of type I?
