A microbiologist wants to better understand how a new vaccine can help patients develop immunity against an infectious disease. For this, s/he needs 3 patients who have successfully developed immunity with the help of the new vaccine and therefore starts vaccinating a group of voluntary patients one-by-one until s/he reaches the required 3 immune patients. It is found that there is 1/3 probability that a vaccinated patient will develop immunity. The probability that the microbiologist will need to vaccinate 8 voluntary patients is (Round to four decimal places, including any zeros.)

A local fan club plans to invest 19,429 to host a soccer game. The total revenue from the sale of tickets is expected to worth 70,182. But if it rains on the day of the game, they won't be able to sell any tickets, and the club will lose all the money invested. If the weather forecast for the day of the game is with 15 chance of rain, calculate to see if there is going to be an expected profit or an expected loss. Note: Please avoid rounding numbers in the middle of your calculations.
A construction company employs two sales engineers. Engineer 1 does the work of estimating cost for 70% of jobs bid by the company. Engineer 2 does the work for 30% of jobs bid by the company. It is known that the error rate for engineer 1 is such that 0.02 is the probability of an error when he does the work, whereas the probability of an error in the work of engineer 2 is 0.04. Suppose a bid arrives and a serious error occurs in estimating cost. What is the probability that Engineer 1 did the work?
A laboratory research group did a microarray experiment five years ago with 10 subjects in the normal group, and 6 subjects in the diet group; one microarray per subject. They never published their results because they felt like their diet group was too small. Now they have more money and they want to get 4 diet animals, and run 4 new microarrays on those animals. They plan to add that data to their study so they can increase their statistical discovery power, and finally publish their results. Although increasing the number of subjects should increase the statistical power of the study, give a reason why increasing the number of samples might NOT result in more significant results.
If an affected female XLX marries an unaffected male XY, what is the probability of passing the hypertrichosis gene to her offspring? Remember hypertrichosis is an X-linked dominant disease. If an affected male XLY marries an unaffected female XX, what is the probability of passing the hypertrichosis gene to his offspring?
In the sport of basketball, a player will sometimes get the opportunity to shoot two free throws without being affected by any other players in the game. Assume that, for one player, these two free throws are independent of each other. If this player makes free throws 80% of the time, what is the probability that this player will make neither free throw in the opportunity?
A rapid HIV test that gives results while a client at a clinic waits is unfortunately less accurate than slower lab tests.Applied to people who have no HIV antibodies,one rapid test has probability about 0.004 of producing a false positive.if a clinic tests 200 people who are free of HIV antibodies,what is the chance that at least one force positive will occur?
In China approximately 70% of people are vaccinated. The current infection rate from the disease is about 2 per thousand people per day, shared between those that are unvaccinated and those vaccinated. the probability of getting infected if not vaccinated is 10 times larger than the probability of getting infected if not vaccinated. a/given the total infection rate and vaccination what would be the infection rate among the vaccinated? b/ if someone gets infected what is the probability that they were vaccinated? c/ draw a fiag
Ezra buys a bag of cookies that contains 9 chocolate chip cookies, 7 peanut butter cookies, 4 sugar cookies and 4 oatmeal cookies.What is the probability that Ezra reaches in the bag and randomly selects a peanut butter cookie from the bag, eats it, then reaches back in the bag and randomly selects a chocolate chip cookie? Give your answer as a fraction, or accurate to at least 4 decimal places.
An undergraduate business student has purchased a laptop computer for use during exams. This laptop is perfectly reliable except for two parts: its microchip, which has a MTBF = 25 hours and its battery, which has a MTBF = 30 hours. Assuming that a new battery has just been installed, what is the probability that the battery will FAIL during a 3 hour exam?
