It is known that 2% of all tests for the COVID-19 virus are positive. Out of the 50 people with Covid-19, 80% of them will have a positive test result. Out of 2450 people without Covid-19, 100% of them will have a negative test result. If a random individual out of 2500 is tested, a. What is the probability that he/she tests negative?(Round your answers to three decimal places.) b. If it is known that the individual tests negative, what is the probability that he/she has carries the Covid-19 virus?(Round your answers to three decimal places.)

Q. 1 It is estimated that 80% of emails are spam emails. Some software has been applied to filter these spam emails before they reach our inbox. A certain brand of software claims that it can detect 99% of spam emails, and the probability for a false positive (a non-spam email detected as spam) is 5%. Now if an email is detected as spam, then what is the probability that it is in fact a non-spam email? event A: email is spam; event B: email is detected as spam. Assume that
In screening for a covid-19, the probability that a healthy person wrongly gets a positive result is 0.04. The probability that a diseased person wrongly gets a negative result is 0.002. The overall rate of the disease in the population being screened is 1%. If my covid-19 test gives a positive result, what is the probability I actually have the disease?
In a specific type of electronic card, the probability of a transistor being defective is 0.01. Let's assume there are 200 transistors on the electronic card. If there are no defective transistors, the electronic card is considered to be functioning. What is the probability of any electronic card not functioning?

Let's calculate the probability of finding someone special. Using a form of Fermi's Paradox (the difference between having limited or no choices to having high amount of choices). Let's calculate your probability using the following data. Multiply the number and all percentages together N (subscript p): Number of people = your target population (number of people in your state). Broward County, FL is 1,953, 251 million. Dade County, FL is 2,717,251 million. Palm Beach County, FL is 1, 497,251 million. Harris County, TX is 4,731,251 million. (example: 1,374,251 x .5 x .44 x .37 x .25 x.10 x.10 = 279 people are potential special people for you) times f (subscript g) = target gender (multiply as a decimal. Example: 0.5 for either sex or 1.0 for both sexes) times f (subscripts) = single people (multiply as a decimal) About 44% of people are single at any given time. f (subscript e) = the number of people you'll run into (multiply as a decimal). Your sample size will be small if you only…
The hospital records show that 75% of patients suffered from COVID-19 dies. What is the probability that 4 out of 6 randomly selected patients will recover?
Let’s assume that the “prevalence” (i.e., the proportion of infected people) of COVID-19 in a particular area is 5%. Tests are randomly administered in this area (i.e., regardless of whether a person is symptomatic or not). The test has a 1% false positive rate and a 4% false negative rate. If a person tests positive, what is the probability that he or she is actually infected with COVID-19?
