1. An investor expects a mean cash flow in time period 3 from an investment project of $70,000. What is the probability that the cash flow in time 3 will be less than $30,000 and greater than 110,000? The probability distribution of cash flows is approximately normal. The standard deviation of expected returns for this time period is $20,000.

z = 1 Probability = 0.3413

z = 2 Probability = 0.4772

z = 3 Probability = 0.4987
