- In a clinical study, volunteers are tested for a gene that has been found to increase the risk for a disease. The probability that a person carries the gene is 0.1. (a) What is the probability 4 or more people will have to be tested before 2 with the gene are detected? (b) How many people are expected to be tested before 2 with the gene are detected?In the past 20 races, there was two A-class horses to participate in each race. And there was ten A-class horse in total won champion (first place) in the past 20 races, According to the aforesaid past data, what is the probability that a A- class hose can win champion in the next race?A true/false test has 15 questions on it. What is the probability that you get at least 13 right by purely guessing?
- In average the number of people entering the intensive care unit at the particular hospital on any one day is 5 persons per day. What is the probability that the number of people entering the intensive care unit one particular day is two?What is the probability that A or B3 occurs?Given that B2 has occurred, what is the probability that A occurs?

Over the past six months, 70 flights on one route arrived early, 150 arrived on time, 15 were late, and 25 were canceled. What is the probability that a flight is early? On-time? Late? Canceled? Are these outcomes mutually exclusive? What is the probability that a flight is either early or on time? How can I calculate this problem in excel since it is business statistics?

- You have a blood test for a rare disease that occurs by chance in 1 person in 100,000. If you have the disease, the test will report that you do with probability 0.95 (and that you do not with probability 0.05). If you do not have the disease, the test will report a false positive with probability 0.001. If the test says you do have the disease, what is the probability that you actually have the disease?In a certain examination 7% of the candidates failed in Science, 17% failed in English and 4% failed in both Science and English.
