- The probability that a student will pass in the Economics test is 2/3, and that a vill not pass in the English test is 5/9. If the probability of his passing in at ne ane of these two tests is 4/5 , find the probability that he will pass in both 20 is the tests. CS Scanned with CamScannerWhat is the probability that X equal 2?Use Tchebycheff's inequality to find how many times a fair coin must be tossed in order that the probability that the ratio of the number of heads to the number of tosses will lie between 0.45 and 0.55 will be at least 0.95.
- Suppose the probability that a male develops some form of cancer in his lifetime is 0.4573. Suppose the probability that a male has at least one false positive test result (meaning the test comes back for cancer when the man does not have it) is 0.51, and that this probability is independent of the probability that a male will develop cancer in his lifetime. • C = a man develops cancer in his lifetime• F = a man has at least one false positive Part (a) Construct a tree diagram of the situation. P(C) = P(F | C) = P(F | C' ) If a test comes up positive, based upon numerical values, can you assume that man has cancer? Justify numerically and explain why or why not. -You cannot assume the man has cancer because there is not enough information given. -You cannot assume the man has cancer because there is a 51% chance that the test is false. -You cannot assume the man has cancer because both the probability of developing cancer in his lifetime and the probability of…) If the probability of a person getting a job is x / 3 The probability of not getting a job is 2/3 . So what is the value of xFindi) the joint probability function of ?1and ?2.ii) the probability that less than 3 heads will occur and the student will win R1 or less.
- Suppose a coin with Pr[H] = 2/3 is flipped 3 times. Using a tree, find the probability that heads was flipped two of the three times.A coin with p{h} = p = 1 - q is tossed n times. Show that the probability that the number of heads is even equals 0.5[1 + (q - p)"].Use calculator to find the probability indicated (keeping 4 decimals): a)P(Z<-1.17) b)P(Z<-0.05) c)P(Z>-2.43)
- Assume that when human resource managers are randomly selected, 56% say job applicants should follow up within two weeks. If 5 human resource managers are randomly selected, find the probability that at least 3 of them say job applicants should follow up within two weeks. The probability is ☐ (Round to four decimal places as needed.)pls help me and write the solution down on a paper if you can thank youAssume that when adults with smartphones are randomly selected, 53% use them in meetings or classes. If 10 adult smartphone users are randomly selected, find the probability that at least 3 of them use their smartphones in meetings or classes.
