A company manufactures transistors in four factories producing 10%, 30%, 40% and 20% of the parts respectively. Due to their respective age and level of standards, factories produce defective parts at frequencies different, i.e. 0.15, 0.20, 0.08 and 0.10. If we take a part at random from among those that are defective, what is the probability that it comes from factory 3?

Car tyres come in many different brands. Even on a car, the tyres can wear out after travelling different distances, due to cornering, braking and wheel alignment. Manufacturers of car tyres are interested in the average distance in kilometres travelled by tyres, or the lifetime of tyres until they are considered un-usable and need to be replaced. At this time a tyre is considered un roadworthy
1.1.3 If 60% of the population of the US need to have their vision corrected, we say that the probability that an individual chosen at random from the population needs vision correction is P(C)=.60. a. Estimate the probability that an individual chosen at random does not need vision correction. b. If 3 people are chosen at random from the population, what is the probability that all 3 need correction? c. If 3 people are chosen at random from the population, what is the probability that the second person does not need correction but the first and third do? d. If 3 people are chosen at random from the population, what is the probability that 1 out of 3 needs correction?
When a scientist conducted a genetics experiments with peas, one sample of offspring consisted of 927 peas, with 723 of them having red flowers. If we assume, as the scientist did, that under these circumstances, there is a 3/4 probability that a pea will have a red flower, we would expect that 695.25 (or about 695) of the peas would have red flowers, so the result of 723 peas with red flowers is more than expected. a. If the scientist's assumed probability is correct, find the probability of getting 723 or more peas with red flowers. b. Is 723 peas with red flowers significantly high? c. What do these results suggest about the scientist's assumption that 3/4 of peas will have red flowers?
To study the hormonal regulation of a metabolic line, albino rats are injected with a drug that inhibits the synthesis of proteins in the organism. In general, 8 out of 30 rats die from the drug before the experiment is over. If 10 animals are treated with the drug. What is the probability that 4 or fewer arrive alive at the end of the experiment? What is the probability that more than 8 will arrive alive at the end of the experiment? Note: Answer with at least 4 decimal places

A Gallup Poll found that 0.07 of teenagers (ages 13 to 17) suffer from arachnophobia and are extremely afraid of spiders. At a summer camp there are 11 teenagers sleeping in each tent. Assume that these 11 teenagers are independent of each other. Calculate the probability that at most 3 of them suffers from arachnophobia in testing this the third time. the topic is bayesian updating.
A particular telephone number is used to receive both voice calls and fax messages. Suppose that 25% of the incoming calls involve fax messages, and consider a sample of 25 incoming calls. (Round your answers to three decimal places.) (I have figured out a-c but need help answering part "d") (d) What is the probability that more than 6 of the calls involve a fax message?
