Researchers often enter a lot of data into statistical software programs. The probability of making zero to two errors per 1,000 keystrokes is 0.49, and the probability of making three to five errors per 1,000 keystrokes is 0.26. Find the probabilities (per 1,000 keystrokes) associated with each of the following.
(a) at most two errors (b) at least three errors (c) at most five errors (d) more than five errors

2. Investment timing options Companies often need to choose between making an investment now or waiting till the company can gather more relevant information about the potential project. This opportunity to wait before making the decision is called the investment timing option. Consider the case: General Forge and Foundry Co. is considering a three-year project that will require an initial investment of $41,000 If market demand is strong, General Forge and Foundry Co. thinks that the project will generate cash...
