100 integrated circuits of type A, 200 of type B, and 300 of type C are mixed together. Type A chips are known to be defective with probability 1/10, type B with probability 1/20, and type C with probability 1/30. a) If all 600 chips are mixed together and one is selected at random, what is the probability of its being defective? b) Given that the selected chip in part (a) is defective, what is the probability that it is type A?

) Mars, Inc. states that 24% of its M&M plain candies are blue and that 16% are green. Assume that they are correct and a large random sample of plain M&Ms is randomly selected from the factory.a.) What is the probability that three candies selected from the sample will be either both greenor both blue?b.) What is the probability that if four candies were selected from the sample that at least onewould be not green and not blue?c.) What is the probability that if twenty M&Ms were eaten randomly from the sample, thatexactly six of them would be green? d.) Find the mean and standard deviation for the above binomial probability distribution inpart c. Based on that, would it be unusual that exactly six would be green from a randomselection of twenty M&Ms? Why or why not?
8) In a class of 100 half the students are science majors and half are liberal art majors. A student who is a science major has a 0.9 probability of passing a given test whilst a student who is liberal art major has only a probability of 0.7. We pick 2 students at random without replacement and give them the test. What is the probability that both students pass the exam?

1- A clinical trial was conducted among 178 patients with advanced melanoma. There were two treatment groups. Group A received lnterleukin-2. Group B received lnterleukin-2 plus a vaccine. If the probability of the positive response is 0.65, then: i) lf 20 melanoma patients are given lnterleukin-2 plus a vaccine, what is the probability that exactly 5 of them will have a positive response to treatment? ii) lf 20 melanoma patients are given lnterleukin-2 plus a vaccine, what is the probability that at least 3 of them will have a positive response to treatment? iii) Prepare a 95% interval estimation for the probability of positive response to treatment in (i).
Human blood may contain either or both of two antigens, A and B. Blood that contains only the A antigen is called type A, blood that contains only the B antigen is called type B, blood that contains both antigens is called type AB, and blood that contains neither antigen is called type O. At a certain blood bank, 35% of the blood donors have type A blood, 10% have type B, and 5% have type AB. a) What is the probability that a randomly chosen blood donor is type O? b) A recipient with type A blood may safely receive blood from a donor whose blood does not contain the B antigen. What is the probability that a randomly chosen blood donor may donate to a recipient with type A blood?
11. A car hiring company has 12 Tata sumos and 8 Qualis. If 5 of these cars go to workshop for repairs and Tata Sumo is as likely to be in for repair as a Qualis, what is the probability that (i) 3 of them are sumos and 2 are Qualis; (ii) at least three of them are sumos and (iii) all of them are of same make.
a) A certain company sends 40% of its overnight mail parcels via express mail service E₁. Of these parcels, 2% arrive after the guaranteed delivery time( L - the event late delivery). If a record of overnight mailing is randomly selected from the company's file, what is the probability that the parcel went via E, and was late? Suppose that 50% of the overnight parcels are sent via express mail E, and the remaining 10% are sent via E3 Of those sent via E₂, only 1% arrive late, whereas 5% of the parcels handled by E, arrive late. b) What is the probability that a randomly selected parcel arrived late? c) If a randomly selected parcel has arrived on time, what is the probability that it was not sent via E₁.
Sadie inspects a batch of products by sampling 4 of them without replacement. If at least one of the products is defective in the sample, the whole batch is sent back.Sadie doesn't know it, but in the batch she is inspecting now, there are 100 products and 11 are defective. If she samples 4 products from this batch without replacement,what is the probability that... a) All of the products in the sample will be defective? b) None of the products in the sample are defective? c) At least one of the products is defective and the whole batch is sent back? For all of the above, round to four decimal places.
