A box contains 100 microchips, some of which were produced by factory 1, some by factory 2, and therest by factory 3. Some of the microchips are defective and some are non-defective. An experimentconsists of choosing one microchip at random from the box and testing whether it is good or defective.Let A be the event 'obtaining a defective microchip'. Let B1 be the event 'the microchip was produced byfactory 1', B2 be the event 'the microchip was produced by factory 2' and B3 be the event 'the microchipwas produced by factory 3'.

A company makes pens called “Surprise Ink.” All of these pens look identical on the outside, but they contain ink that is one of the following colors: blue, red, green, or purple. A teacher has 16 of these pens: 2 purple, 6 blue, 5 red, and 3 green.

A big bowl contains 3 red chips and 6 white chips. A chip is drawn at random. If it is red, that chip along with an additional red chip will be put back in the bowl. If it is white, the chip is simply returned to the bowl. Next a second chip is drawn. If the 2nd chip is white, what is the probability that the first is red? The answer as 9/29. But I don't know the work.
One student is selected at random from a group of 200 known to consist of 140 full-time (80 female and 60 male) student and 60 part-time (40 female and 20 male) students. Event A is "the student selected is full-time" and event C is "the student selected is female". (a) Are events A and C independent? (b) Find the probability of one student selected is full-time, that should be female.
For curing a certain engineering material, there are 7 standard treatments A, B, C, D, E, F & G. An engineer has the resources for conducting a comparative study of 7 of these treatments. If he chooses the 5 treatments for study at random, what is the probability that treatments A and C will be chosen?
Suppose that 3 out of 19 doctors in a small hospital are trained in special procedures, 12 of the doctors are over the age of 40 and 2 is both trained in special procedures and over 40.

A company published the results of a study that found that arrogant workers are more likely to have poor performance ratings. Suppose that 15% of all full-time workers exhibit arrogant behaviors on the job and that 13% of all full-time workers will receive a poor performance rating. Also, assume that 10% of all full-time workers exhibit arrogant behaviors and receive a poor performance rating. Let A be the event that a full-time worker exhibits arrogant behavior on the job. Let B be the event that a full-time worker will receive a poor performance rating. Are events A and B independent? Why? Are the events A and B independent? Explain. A. No, because if workers exhibit arrogant behaviors, they are more likely to receive a poor performance rating. B. No, because if workers exhibit arrogant behaviors, they will receive a poor performance rating. C. Yes, because if workers exhibit arrogant behaviors, they are more likely to receive a poor performance rating. D. Yes, because if workers…
