It is said that it usually takes three years for the accident vehicle to be repaired.What is the probability that the repair of an accident vehicle will be completed within 5 hours? (Do not calculate the value of the natural constant e, but still hold)
The Denver Post reported that, on average, a large shopping center had an incident of shoplifting caught by security 2.1 times every two hours. The shopping center is open from 10 A.M. to 9 P.M. (11 hours). Let r be the number of shoplifting incidents caught by security in an 11-hour period during which the center is open. What is λ? (Use 2 decimal places.)(b) What is the probability that from 10 A.M. to 9 P.M. there will be at least one shoplifting incident caught by security? (Use 4 decimal places.)(c) What is the probability that from 10 A.M. to 9 P.M. there will be at least three shoplifting incidents caught by security? (Use 4 decimal places.)
The probability of a false positive test result is 0.168 (Round to three decimal places as needed.) Who would suffer from a false positive result? Why? O A. The person tested would suffer because he or she would not be suspected of using drugs when in reality he or she does use drugs. O B. The employer would suffer because the person tested would be suspected of using drugs when in reality he or she does not use drugs. O C. The person tested would suffer because he or she would be suspected of using drugs when in reality he or she does not use drugs. O D. The employer would suffer because the person tested would not be suspected of using drugs when in reality he or she does use drugs.

Suppose a fair coin is tossed 3 times. Define the r.v.'s X = number of Heads and Y = 1(0) if H (T) occurs on the first toss. Find the joint probability function for (X, Y).
Q: A certain virus infects one in every 20 people. A test used to detect the virus in a person delivers positive outcome at 85% accuracy for infected persons. Moreover, it provides negative outcome for healthy persons at 95% accuracy. Compute followings: Find the probability that a person has the virus given that his test outcome is positive. Find the probability that a person does not have the virus given that his test outcome is negative. Find the probability that a person has the virus given that his test outcome is negative.

Q. 1 t is estimated that 809% of emails are spam emails. Some software has been applied to filter these spam emails before they reach our inbox. A certain brand of software claims that it can detect 99% of spam emails, and the probability for a false positive (a non-spam email detected as spam) is 5%. Now if an email is detected as spam, then what is the probability that it is in fact a non-spam email? event A: email is spam; event B: email is detected as spam. Assume that
The statement below is true/false: A type II error is defined as rejecting H1 when it is true. Producers’ risk in rejecting product with good quality is a type I error. Power of a test is the probability of accepting H0 when it is false
The reported rate for colorblindness for men ages 65 and older is 12%. Assume this estimate is the true population proportion of men ages 65 and older. A SRS of 25 men ages 65 and older is taken. Calculate the probability that proportion of men ages 65 and older who have colorblindness is more than 0.10. A. 3783 B. 6217 C. This can’t be done because np is not greater than D. This can’t be done because n is not greater than 30 and we are not told that the variable is normally distributed.
An unfair coin with Pr[H] =0.4 is flipped. If the flip results in a head, a marble is selected at random from a urn containing two red and eight blue marbles. Otherwise, a marble is selected from a different urn containing five red and three blue marbles. If the selected marble selected is red, what is the probability that the flip resulted in a head?
A screening test for a particular infectious disease shows a positive test result in 90% of all cases when the disease is actually present, and in 10% of all cases when it is not. Assume that t% of the population is infected, where t is = 1. For a randomly chosen from the population person, find the probability that the person is actually infected if the test shows positive.
