It is January 1 of year 0, and Merck is trying to determine whether to continue development of a newdrug. The following information is relevant. You can assume that all cash flows occur at the ends of therespective years.■ Clinical trials (the trials where the drug is tested on humans) are equally likely to be completed in year1 or 2.■ There is an 80% chance that clinical trials will succeed. If these trials fail, the FDA will not allow thedrug to be marketed.■ The cost of clinical trials is assumed to follow a triangular distribution with best case $100 million,most likely case $150 million, and worst case $250 million. Clinical trial costs are incurred at the end ofthe year clinical trials are completed.■ If clinical trials succeed, the drug will be sold for five years, earning a profit of $6 per unit sold.■ If clinical trials succeed, a plant will be built during the same year trials are completed. The cost of theplant is assumed to follow a triangular distribution with best case $1…
