Lucky Enterprises is using a discounted cash flow model. Identify which model Lucky might use to estimate the discounted fair value under each scenario, and calculate the fair value using the present value tables:Scenario $1$: Cash flows are fairly certainScenario $2$: Cash flows are uncertain$$100/$year for $5$ years$75\%$ probability that cash flows will be $$100$ in $5$ yearsRisk$-$adjusted discount rate is $6\%$Risk$-$free discount rate is $3\%25\%$ probability that cash flows will be $$75$ in $5$ yearsRisk$-$adjusted discount rate is $6\%$Risk$-$free discount rate is $3\%$
