There are two lots of items; it is known that allthe items of one lot satisfy the technicalstandards and 1/4 of the items of the other lotare defective. Suppose that an item from a lotselected at random turns out to be good. Findthe probability that a second item of the samelot will be defective if the first item is returnedto the lot after it has been checked.

Suppose 5 out of every 10,000 individuals in a country has a rare disease. A test for the disease exists. Individuals known to have the disease test positive 99% of the time. Individuals known to be free of the disease test negative 98% of the time. Suppose an individual from the country is selected at random (with all being equally likely to be selected) and given the test. Given that the individual tests positive, what is the probability that he in fact has the disease? Give the probability as a decimal number to six decimal places.
Suppose that 45% of all babies born in a particular hospital are girls. If 7 babies born in the hospital are randomly selected, what is the probability that fewer than 2 of them are girls? Carry your intermediate computations to at least four decimal places, and round your answer to two decimal places.
Suppose two friends, Michael and Austin, are arguing about Michael's supposed trivia prowess. Michael, a trivia fanatic, wishes to prove his vast trivia knowledge by answering a series of trivia questions. To test this, Austin purchases a book of trivia questions and randomly selects 75 to ask Michael. Assume that for each question, the probability that Michael gives the correct answer is 0.80. What is the probability that Michael will answer at least 55 questions correctly? Use the normal approximation to obtain the result. Give your answer as a decimal precise to at least three decimal places.
Assume for this problem that the company has 8 BMWs and 5 Hondas, and two cars are selected randomly and given to sales representatives. What is the probability of both cars being BMWs, given that both are of the same make?
Testing for a disease can be made more efficient by combining samples. If the samples from six people are combined and the mixture tests negative, then all six samples are negative. On the other hand, one positive sample will always test positive, no matter how many negative samples it is mixed with. Assuming the probability of a single sample testing positive is 0.05, find the probability of a positive result for six samples combined into one mixture. Is the probability low enough so that further testing of the individual samples is rarely necessary? The probability of a positive test result is (Round to three decimal places as needed.)

A university computer laboratory installs one of three operating systems on each computer used in the lab. It is known from product testing that during an hour of web browsing the probability a computer with system 1 installed will crash is 0.15, the probability of a computer with operating system 2 crashing is 0.08 and the probability of a computer with system 3 crashing is 0.1. Operating systems 1 and 3 are installed on the same number of computers while system 2 is installed on twice as many computers as system 1 (or system 3).a) What is the probability that a randomly selected computer crashes during an hour of web browsing?b) If a computer selected at random crashed during an hour of browsing the web, what is the probability it has operating system 2 installed?c) If a computer selected at random does not crash during an hour of web browsing what is the probability it has operating system 1 or operating system 2 installed?
