The proportion of people in a given community who have Covid-19 infection is 0.005. A test is available to diagnose the disease. If a person has Covid-19, the probability that the test will produce a positive signal is 0.99. If a person does not have the Covid-19, the probability that the test will produce a positive signal is 0.01. a) What is the probability that the test will generate positive signal? b) Which model/rule will best be good for solving the above problem and why? c) Comment on the types of events you see in the problem and name them.

Mendel found no dominance in snapdragons with respect to red and white flower color. When pure red (RR) and pure white (rr) parents are crossed, the resulting Rr combination (one of each gene) produces second generation offspring with pink flowers. Suppose one of these second generation pinks is crossed with a pure red. What is the probability that the resulting snapdragonn will have white flowers?
The probability that I park my car in a garage on Monday is .3. The probability that I park my car in a garage onTuesday is .25. If parking my car in a garage on Tuesday is independent of my parking my car in a garage onMonday, what is the probability that I neither park my car in a garage on Monday nor on Tuesday?
Trisomy 18 (T18) is a rare genetic disorder that severely disrupts a baby's development prior to birth. Many die before birth and most die before their first birthday. T18 occurs in only 1 in 2500 pregnancies in the U.S. A genetic test on the mother's blood can be done to test for T18 in her baby. The overall probability of a positive test result is 0.010384. The probability of a positive test result for a baby with T18 is 0.97. The probability of a negative test result for a baby without T18 is 0.99. A mother's blood tests positive for T18. What is the probability that her baby has T18? (A) 0.0004 (B) 0.0374 (C) 0.4902 (D) 0.97 (E) 0.99
When LeBron James shoots a free throw, he hits with a probability of 0.9 and misses with a probability of 0.1. Assume that the result of his previous free throw (whether a hit or a miss), does not affect the probability with which he hits the current throw, i.e., for any free throw he shoots, he hits with a probability of 0.9 and misses with a probability of 0.1. When he hits a free throw, he makes one point and when he misses a free throw, he makes zero points. Answer the following questions with this information. Let P1 denote a random variable that represents the number of points LeBron James makes when he shoots only one free throw. 1. How many possible values can P1 take? Develop a probability distribution for P1 (Very important: Enter the values of P1 in increasing order as you go down in the table) P1 f(P1) (1 decimal) (1 decimal)
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?
Based on a smartphone survey, assume that 45% of adults with smartphones use them in theaters. In a separate survey of 215 adults with smartphones, it is found that 94 use them in theaters. If the 45% rate is correct, find the probability of getting 94 or fewer smartphone owners who use them in theaters. Is the result of 94 significantly low? If the 45% rate is correct, the probability of getting 94 or fewer smartphone owners who use them in theaters is ___. Is the result of 94 significantly low? ___, because the probability of this even is ____ than the probability cutoff that corresponds to a significant event, which is ___ (Yes, No) (Greater, Less) (.5, 0.05, 1)
A rare disease exists with which only 1 in 500 is affected. A test for the diseaseexists, but of course it is not infallible. A correct positive result (patient actually has the disease) occurs 95% of the time, while a false positive result (patient does not have the disease) occurs 1% of the time. If a randomly selected individual is tested and the result is positive, whatis the probability that the individual has the disease?
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?
During a fitness center outbreak, 1/10 of the customers of thecenter are infected by COVID-19. Depending on whether the customeris infected or not, the probability that he/she has flu symptoms are 0.8and 0.3, respectively. If a random customer does not have flu symptoms, what is the probability that he/she is infected?
A certain typing agency employs two typists. The average number of errors per article is 1.21.2 when typed by the first typist and 55 when typed by the second. If your article is equally likely to be typed by either typist, find the probability that it will have no errors.
Suppose 10% of a city’s inhabitants have contracted Covid-19 but are asymptomatic (do not show any symptoms). A PCR test for detecting Covid will return a positive result for 90% of the people with asymptomatic Covid and is negative for 90% of people who are not infected. What is the probability that a person for whom the test result is negative, actually has indeed contracted Covid-19?
