What is the probability that a randomly selected student does not have a Microsoft product and does not have an Apple product (does not have either product). On a large university campus, 84% of students report having a Microsoft product (phone,computer, mp3 player, etc.) and 33% report having an Apple product. Also, 86% reporthaving a Microsoft or Apple product.A student is randomly selected from this campus. Define the following events:A = the randomly selected student has a Apple product.B = the randomly selected student has an Microsoft product.

A particular team sport declares the team that wins 4 games out of 6 possible games as the champion. The championship ends once a team has won 4 games. Suppose that teams X and Y face each other in the championship games and that team X has 65% probability of winning a game over team Y. What is the probability that team X wins the championship in 5 games?
Composite blood testing is sometimes used to save costs. A Hepatitis-C composite blood test means that when several blood samples are mixed together and tested for Hepatitis- C. The probability of testing positive for Hepatitis-C in a certain population is 0.490. If 4 bloodsamples are mixed together, what is the probability that composite sample would be positive (in other words, what is the probability that at least one of the people in the group is positive for Hepatitis-C)?

A WAL*MART manager has five good light bulbs and four defected light bulbs in Box 1 and four good light bulbs and five defected light bulbs in Box 2. If the manager transfers one light bulb at random from Box 1 to Box 2, what is the probability of his then drawing a good light bulb from Box 2? (Round to four decimal places. Do not use %)
A poll conducted on the proposed bonus plan for employees indicated that 40% of all female employees and 65% of all night-shift employees supported the plan. Also, 34% of all employees are women, 51% of all employees are night-shift workers, and 24% are day-shift females. If two employees are randomly selected, what is the probability that the first, a male is a night-shift worker and the second, a female is a day-shift worker? Answer:

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?
