**Probability of Having Covid-19 with a Positive Test Result**The Curative nasal swab test offered by UTA for Covid-19 testing has a false positive rate of 2% and a false negative rate of 5%. Assume that Javier takes this test at a time when 1% of UTA students are actively infected with Covid-19. If Javier's test is positive for Covid-19, to the nearest 3rd decimal place, what is the probability that Javier actually has Covid-19 at the time of testing?- ☐ 0.677- ☐ 0.324- ☐ 0.500- ☐ It cannot be from the given information.

Answered: with Covid-19. If Javier's test is…

A sample of 400 adults found that 82 have high blood pressure. However, 98 of those studied reported being unwilling to change their diet. Based on this sample, if an adult is chosen at random, what is the probability that he or she is open to trying to eat more healthfully? Express your answer as a fraction in lowest terms or a decimal rounded to the nearest millionth.
Radioactive atoms are unstable because they have too much energy. When they release their extra energy, they are said to decay. When studying cesium-137, a nuclear engineer found that 22,713 radioactive atoms decayed over 365 days. On a given day (use for n), find the probability that 50 (use for r) radioactive atoms decayed. (When calculating, use lambda rounded to two decimal places and probability rounded to three decimal places)
Covid-19 tests are common nowadays, but some results of tests are not true. Let’s assume; a diagnostic test has 99% accuracy and 60% of all people have Covid-19. If a patient tests positive, what is the probability that they actually have the disease?
From observations of the weather, it is known that on October 20 the probability of rain is 0.85. A certain forecast method for October 20 is correct 0.9 times if rain is predicted and 0.75 times if no rain is predicted. How much information does a real weather forecast provide 20 th of October?

Eight students attended a birthday party. Three of them were confirmed Covid-19 positive. The contact tracer had conducted a random test for only two students. Find the probability distribution for random variable X which represents the number of Covid-19 positive patients. What three statements of the problem can be concluded out of the topic Covid-19?
Suppose that the probability an archer will hit a target is 0.80 and that each shot is independent. If the archer shoots 6 times, what is the probability she hits the target at least 5 times? (Round your answer to three decimal places.)
A new medical test has been designed to detect the presence of the mysterious Brainlesserian disease. Among those who have the disease, the probability that the disease will be detected by the new test is 0.82. However, the probability that the test will erroneously indicate the presence of the disease in those who do not actually have it is 0.08. It is estimated that 18 % of the population who take this test have the disease. If the test administered to an individual is positive, what is the probability that the person actually has the disease?
