A venture capital firm evaluates thousands of startup companies each year. Historically, only 1 out of every 1,000 startups turns out to be successful. The firm uses an initial evaluation test to assess potential. The evaluation test is imperfect: If a startup will be successful, the test returns a positive evaluation with probability 0.8 If a startup will not be successful, the test returns a positive evaluation with 0.05 Show your work on the scratch paper answering Q4-Q6.
