The state medical school has discovered a new test for tuberculosis. Experimentation with this new test has shown that the probability of a positive test result for tuberculosis when a person actually has it is 0.82. The probability of a false positive test result is 0.09. It is presumed that 4% of the population has tuberculosis. If a person is chosen at random, what is the probability that he/she a.) has tuberculosis and a positive test? b.) has a positive test and does not have tuberculosis? c,) tests negative for tuberculosis?

A study published in 2012 concluded that 33 percent of the patients on Prednisone, a medication used for the treatment of various allergic disorders, suffered adverse effects. If 90 patients with allergic disorders are selected randomly and administered Prednisone, what is the approximate probability that at most 20 of them will suffer adverse effects? 0.022 0.330 0.670 0.015 0.042
At a bakery, a customer with a purchase amount of under $20 has a probability of 0.35 of using a credit card for the purchase, while a customer with a purchase amount of $20 or over has a probability of 0.6 of using a credit card for the purchase. Data shows that 80 % of purchases at the bakery are under $20. Given that a customer uses a credit card for a purchase, find the probability that the purchase amount was $20 or over. Give the probability as a decimal, and if rounding give to 4 decimal places.
