During any given year, each stock in a portfolio will either increase in value or decrease in value (no stock will remain exactly even). Assume that each stock in the portfolio has a 64% chance of increasing in value. The portfolio contains four different stocks and the stock prices are independent of each other.
(a) What is the probability that all of the stocks decrease in value during the year? (Round answer to four decimal places.)
(b) What is the probability that at least one of the stocks will increase in value during the year? (Round answer to four decimal places.) (c) What is the probability that at least one of the stocks will decrease in value during the year? (Round answer to four decimal places.)
