- Atlanta experiences an average of one ice storm every 5 years. What is the probability that Atlanta has two ice storms in the next 3 years?Consider the case where the predetermined average number of bus arrivals at the Cubao Station is 6 per 15-minute period. Find the probability of at least 4 buses arriving in a 15-minute period.Suppose the probability of snow tomorrow is 0.4 while the probability of IU winning the basketball game tomorrow is 0.9. Assuming these events are independent, what is the probability that it snows and IU loses?
- As the number of cars a person owns increases, so does the life expectancy of the person. What is the most likely explanation? Wealth is the common underlying cause Having more cars causes people to live longer. It is a coincidencegive some example of probabilityFor this problem, assume that 11 % withdraw, 14 % receive an A, 18 % receive a B, 35 % receive a C, 14 % receive a D, and 8 % receive an F. (1) What probability should be assigned to the event "pass the course"? (2) What probability should be assigned to the event "withdraw or fail the course"?
- in a quiet group of eight people, the probability of one person starting to speak is 1/3. What is the probability that the number of people speaking is greater than six?A study tracked a large group of people for 10 years. At the start of the study, 20% were heavy smokers (H), 30% were light smokers (L), and 50% were non-smokers (N). The interest of the study was whether the people in the study died during the study (D) or not die (Dc ). The probability that a light smoker died during the study was twice that of the probability of a non-smoker dying. Also, the probability that light smoker died during the study was half that of the probability of a heavy smoker dying. A randomly selected person from the study died during the study. What is the probability that this person was a heavy smoker (given they died, what is the probability they were a heavy smoker H)?Stress at work: In a poll conducted by the General Social Survey, 80% of respondents said that thelr tobs were sometimes or always stressful. Two hundred workers are chosen at random. Use the TI-84 Plus calculator as needed. Round your answer to at least four decimal places. (a) Approximate the probability that 165 or fewer workers find their jobs stressful. (b) Approximate the probability that more than 150 workers find their jobs stressful. (c) Approximate the probability that the number of workers who find their jobs stressful is between 153 and 160 Inclusive. Part 1 of 3 The probability that 165 or fewer workers find their jobs stressful is Part 2 of 3 The probability that more than 150 workers find their jobs stressful is
