An investor is considering a portfolio mix of 70% of stock A and 30% of Stock B. Stock A's returns are expected to be 20%, 10% and 8% in good, average and bad economies respectively.

The probability of a good economy is expected to be 60%, while the average and bad economies have a 20% chance of occurrence. Given this information, calculate the standard deviation of the portfolio.
