In screening for a certain disease, the probability that a healthy person wrongly gets a positive result is0.05. The probability that a diseased person wrongly gets a negative result is 0.002. The overall rate ofthe disease in the population being screened is 1%. If my test gives a positive result, what is theprobability I actually have the disease? ( dont hand writing solution)
The chance of an IRS audit for a tax return with over $25,000 in income is about 2% per year. We are interested in the expected number of audits a person with that income has in a 16-year period.

X=0, 1, 2,..., 15, 16 OX= 1, 2, 3, OX= 1, 2, 3, OX=1,2,3,... 15, 16 98, 99, 100 Part (c) Give the distribution of X X-B 0.02 □ Part (d) How many audits are expected in a 16-year period? (Round your answer to two decimal places.) 0.32 audits Part (e) Find the probability that a person is not audited at all. (Round your answer to four decimal places.) Part (1) Find the probability that a person is audited more than twice. (Round your answer to four decimal places.)
