24When correctly adjusted, a machine that makes widgets operates with a 5% defective rate.However, there is a 10% chance that a disgruntled employee shakes the machine, in whichcase the defective rate jumps up to 30%.(a)Suppose that a widget made by this machine is selected at random and is found tobe defective. What is the probability that the machine had been shaken?

Consider D as an event that machine is defective that is (D=5%) in terms of probability P(D)=0.05…

Answered: When correctly adjusted, a machine that…

Cathy is planning to take the Certified Public Accountant Examination (CPA exam). Records kept by the college of business from which she graduated indicate that 81% of students who graduated pass the CPA exam. Assume that the exam is changed each time it is given. Let n = 1, 2, 3, ... represent the number of times a person takes the CPA exam until the first pass. (Assume the trials are independent.) (a) What is the probability that Cathy passes the CPA on the first try? (Use 2 decimal places.)(b) What is the probability that Cathy passes the CPA exam on the second or third try? (Use 4 decimal places.)

The probability that an individual has 20-20 vision is 0.14. In a class of 77 students, what is the probability of finding exactly 5 people with 20-20 vision? assuming finding an individual with a 20-20 vision is independent of finding another individual with 20-20 vision.
A factory uses a specific machine to produce pieces. From previous data, we know that 97% of the time the machine is set up correctly. If this is the case, it produces 95% acceptable (non-defective) pieces. However, if it is not set up correctly, it produces only 40% of acceptable pieces. Q22 A piece produced by the machine is selected. What is the probability that the selected piece is non-defective? Your answer should be in % and have two digits after the period. So, if your answer is 50.002%, enter 50.00. Your Answer:
When sent a questionnaire, 50% of the recipients respond immediately. Of those who do not respond immediately, 60% respond when sent a follow-up letter. If the questionnaire is sent to 4 persons and a follow-up letter is sent to any of the 4 who do not respond immediately, what is the probability that at least 3 never respond?

Overall, Steve Dalkowski throws a strike with 17% of his pitches (that is, the probability that he throws a strike with any given pitch is .17). (a) In one game, Dalkowski throws 240 pitches. What is the probability that he throws exactly 40 strikes? (b) In one week, Dalkowski throws 400 pitches. What is the probability that he throws 80 or more strikes? Every day for eternity Dalkowski throws 100 pitches, and records the number of strikes. (c) Find the mean µ, and the standard deviation o, of the numbers (of strikes thrown on different days) that Dalkowski records.
