The printing machine consists of three parts A, B, C. The Probability of part A failure is 0.1. Theprobability of failure for B is 0.2 given A is broken, and 0.1 otherwise. The probability of Cfailing is 0.2 given B is broken and 0.1 otherwise. The "call the master" signal lights up if at leasttwo parts out of three are out of order. I can fix the printer if only two parts are broken,otherwise, I will only spoil everything. What is the conditional probability that I don't need toundertake repairs, given that the call the master" signal is on?AnouO

Suppose that the space shuttle has three separate computer control systems. The main system and two backup duplicates of it. The first back up would monitor the main system and kick in in the main system failed. Similarly, the second backup would monitor the first. We can assume that a failure of one system is independent of a failure of another system since the systems are separate. The probability of failure for any one system on any one mission is know to be 0.011. Find the probability that the shuttle is left with no computer control system on a mission.
A class contains 50 students. The probability of failing in one of the courses for each student is 0.035, but there is no chance to fail in more than one course. You know that a student failed in a course, the probability that the fail reason in non-attendance is 0.025. All other fail reasons are low average. The examinations are private, so the results are mutually independent. Let X and Y be the numbers of failed students due to non-attendance and due to low average, respectively, in that class this semester. Find the joint MGF
Refer to the figure below in which surge protectors p and q are used to protect an expensive high-definition television. If there is a surge in the voltage, the surge protector reduces it to a safe level. Assume that each surge protector has a 0.96 probability of working correctly when a voltage surge occurs. Complete parts (a) through (c) below. D-P-q- TV Series Configuration H TV O Parallel Configuration a. If the two surge protectors are arranged in series, what is the probability that a voltage surge will not damage the television? (Do not round.) b. If the two surge protectors are arranged in parallel, what is the probability that a voltage surge will not damage the television? (Do not round.) c. Which arrangement should be used for better protection? O The series arrangment provides better protection because it has a lower probability of protection. The parallel arrangment provides better protection because it has a lower probability of protection. The series arrangment provides…
A sample of liquid has a 10% chance of containing a particular organic pollutant. Assuming that the samples are independent. Determine the probability that in the next 20 samples there are at most two samples contain the pollutant. Solve both in detailed and approximate solutions. Comment on the results.
You are a paranoid delusional statistician with far too much time on your hands. One day, you sit down to have a bowl of soup. This bowl of soup happens to be Tic-Tac-Toe themed, meaning that you stir have some noodles that are shaped like an X, and some that are shaped like an O. As your soup, you notice that this bowl seems to have a particularly high number of X- you shaped noodles in it. Being paranoid, you conclude that this has some meaning-like someone is trying to give you a message, possibly warning you of the dangers of x-rays. You jump out of your seat and run to get your x-ray-proof cape, and then you pause for a moment and think that you should calculate a chi-square statistic for the frequency of X-shaped noodles before freaking out. First, you carefully separate each of the noodles by shape and count them. Here is what you find: Frequency of Noodles X-shaped O-shaped 33 21 1. What type of chi-square design is this (check one box)? OTwo-cell ОThree-cell OTwo-by-two…
An examination consists of two papers , Paper 1 and Paper 2 . The probability of failing in Paper 1 is 0.3 and that in Paper 2 is 0.2 . Given that a student has failed in Paper 2 , the probability of failing in Paper 1 is 0.6 . Then the probability of a student failing in both the papers is equal to
A class contains 30 students. The probability of failing in one of the courses for each student is 0.02, but there is no chance to fail in more than one course. You know that a student failed in a course, the probability that the fail reason in non-attendance is 0.015. All other fail reasons are low average. The examinations are private, so the results are mutually independent. Let X and Y be the numbers of failed students due to non-attendance and due to low average, respectively, in that class this semester. Find the joint MGF
A researcher wonders if there an association between the incidence of colds and the amount of Vitamin C taken. He recruits 93 volunteers and randomly assigns 26 of them to take 500 mg of Vitamin C, 18 of them to take 1000 mg of Vitamin C and the rest to take no Vitamin C. At the end of the study, it was determined that 30 of the volunteers did not have any colds where 15 of them were in the 500 mg group, 11 of them were in the 1000 mg group, and the rest took no Vitamin C. Test the appropriate hypothesis at a = 0.01. Round your answers to three decimal places, if necessary. Fill in the hypotheses below: Ho: There is not vitamin C taken. Ha: There is vitamin C taken. Complete the table of expected counts under the null hypothesis: No Vitamin C 500mg Vitamin C 1000mg Vitamin C No Vitamin C 500mg Vitamin C 1000mg Vitamin C At least one cold 33.194 an association between the incidence of colds and the amount of an association between the incidence of colds and the amount of 17.613 12.194…
3.12 Mark is deciding which route to take to work. His choices are I = the Interstate and F = Fifth Street.• P(I) = 0.44 and P(F) = 0.55• P(I AND F) = 0 because Mark will take only one route to work.What is the probability of P(I OR F)?
Suppose that a new Internet company Mumble.com requires all employees to take a drug test. Mumble.com can afford only the inexpensive drug test—the onewith a 5% false-positive rate and a 10% false-negativerate. (That means that 5% of those who are not usingdrugs will incorrectly test positive and that 10% of thosewho are actually using drugs will test negative.) Supposethat 10% of those who work for Mumble.com are usingthe drugs for which Mumble is checking. (Hint: It maybe helpful to draw a tree diagram to answer the questionsthat follow.)a. If one employee is chosen at random, what is theprobability that the employee both uses drugs and testspositive?b. If one employee is chosen at random, what is theprobability that the employee does not use drugs buttests positive anyway?c. If one employee is chosen at random, what is the probability that the employee tests positive?d. If we know that a randomly chosen employee has testedpositive, what is the probability that he or she usesdrugs?
The CDC (Center for Disease Control) did a study to see if there is an association between lung cancer and exposure to asbestos (this data set has been made up. However, my understanding is that the association has already been proven). The doctors at the CDC took a SRS of 20 people with lung cancer and a SRS of 30 people without lung cancer. Suppose the incidence of lung cancer is 1 out of every 1000 people (I made this number up).Let C = a randomly selected person has lung cancerLet E = a randomly selected person has been exposed to asbestosUse 3 decimal places for the following questions.P(C | E) =
Professor Brown gives her students a maximum of three attempts to pass a final examination in her statistics course. She has found that the probability of passing on the first attempt is 0.40, the probability of passing the second attempt is 0.65 and the probability of not passing the third attempt is 0.15. Find the probability that a randomly selected student of hers will pass the final examination
