QUESTION 9 Sales records of a hobby shop showed the following number of radio-controlled trucks sold weekly for each of the last 50 weeks. What is the probability of selling either 1 truck or 3 trucks in any given week? Number of Trucks Sold Number of Weeks 20 1 15 2 10 4 1 O P{1 or 3 trucks sold} = 15/50 + 4/50 O P{1 or 3 trucks sold} = 15/50 - 4/50 O P{1 or 3 trucks sold} = 15/50 + 10/ 50+ 4/50 O P{1 or 3 trucks sold} = 15/50 x 4/50 34
QUESTION 7 A virus is known to infect a system with probability 60%. A new antivirus is designed for this threat, and it is tested on a number of systems. It is noticed that the probability that the test detects an infected system is 90%, and the probability that it correctly shows negative when a system is not infected is 80%. Use Baeye's rule to calculate the probability that a system is infected if this test indicates so (a positive test). Enter your answer here as a decimal 0.xx (do not enter more than two decimals, and do not enter less; truncate to the first two decimals and don't round up or down)
Question 38. In a hypothesis test, the Type I error rate is a = 0.10. Suppose we also know that the Type II error rate is 0.20 for this test. What is the probability of making Type I and Type II errors at the same time? Put your answer in percentage. If your answer is "12.34%" then put “12.34" in the blan-

The probability that Kedah FC win on a dry day is , whereas the probability that they win on a wet day is -. Kedah FC are due to play their next match on Sunday.
Question 2. A survey found that 62% of callers in the United States complain about the service they receive from a call center if they suspect that the agent who handled the call is foreign.11 Given this context, what is the probability that (state your assumptions) (a) the next three consecutive callers complain about the service provided by a foreign agent? (b) the next two calls produce a complaint, but not the third? (c) two out of the next three calls produce a complaint? (d) none of the next 10 calls produces a complaint?
QUESTION 1 True or False: To say that events A and B are independent is to say that the knowledge that event B occurred does not change the probability of event A occurring. O True O False QUESTION 2 True or False: To say that events A and B are independent means that P(AIB) = P(A). O True O False
QUESTION 9 A 2018 Pew Research survey found that 66.5% of Americans use Facebook and 27,6% of Americans use Linkedln. In addition, 24.8% of Ame and Linkedin.

Question 3 A factory makes electronic control units. The probability that a control unit has a fault is 8%. All devices are tested before they are put into use, but the test does not always give the correct answer. We say that the test fails if the test indicates that the device has a fault. If a device really has a fault, the probability is 88% that the test will fail. If a device is error-free, there is a 95% probability that the test will fail. Only units that the test does not work on are used. Let D be the event that a device has an error, and let T be the event that the test fails. a) Based on the information given above, write down what P(D), P(T|D) and P(T|D) are. Calculate P(D) and P(T|D). What is the probability that the test results in a random unit, P(T)? What is the probability that a device put into service will have a fault?
Question 1 A) An insurance company believes the probability that owners of a certain type of car are involved in an accident in the next year is equal to 0.05. The company sells policies to insure 12 of these cars for a year for at most 1 accident. You may assume all 12 policies are independent.What is the expected number of accidents in the year? B) An insurance company believes the probability that owners of a certain type of car are involved in an accident in the next year is equal to 0.05. The company sells policies to insure 12 of these cars for a year for at most 1 accident. You may assume all 12 policies are independent.What is the variance of the number of accidents in the year? C) An insurance company believes the probability that owners of a certain type of car are involved in an accident in the next year is equal to 0.05.
