A friend who lives in Los Angeles makes frequent consulting trips to Washington, D.C.; 60% of the time she travels on airline #1, 20% of the time on airline #2, and the remaining 20% of the time onairline #3. For airline #1, flights are late into D.C. 25% of the time and late into L.A. 20% of the time. For airline #2, these percentages are 30% and 15%, whereas for airline #3 the percentages are30% and 20%. If we learn that on a particular trip she arrived late at exactly one of the two destinations, what are the posterior probabilities of having flown on airlines #1, #2, and #3? Assume thatthe chance of a late arrival in L.A. is unaffected by what happens on the flight to D.C. [Hint: From the tip of each first-generation branch on a tree diagram, draw three second-generation brancheslabeled, respectively, O late, 1 late, and 2 late.] (Round your answers to four decimal places.)airline #1airline #2airline #3

Aregional automobile dealership sent out fliers to prospective customers indicating that they had already won one of three different prizes: an automob $26,000, a $75 gas card, or a $5 shopping card. To claim his or her prize, a prospective customer needed to present the flier at the dealership's showroc print on the back of the flier listed the probabilities of winning. The chance of winning the car was 1 out of 31,135, the chance of winning the gas card wa 31,135, and the chance of winning the shopping card was 31,133 out of 31,135. Complete parts (a) through (d). a. How many fliers do you think the automobile dealership sent out? Assume there is one car and one gas card available. 31135 fliers b. Using your answer to (a) and the probabilities listed on the flier, what is the expected value of the prize won by a prospective customer receiving a flier u$ 5.84 (Round to the nearest cent as needed) c.

3. The probability that Jaden's dog will wear a collar today is 0.55. The probability that Jaden will take the dog on a walk is 0.3, and the probability that both will occur is 0.25. Are the two events independent? Yes, the events are independent because the product of the probability of each event is 0.25. No, the two events are not independent because the difference of the probabilities of each event is 0.25. No, the two events are not independent because the product of the probability of each event is not 0.25. Yes, the two events are independent because the difference of the probabilities of each event is 0.25.

Labor trends were recently studied using a survey of respondents who were either unemployed (A) or employed (B). The survey results revealed that among those surveyed, 70% of those currently unemployed gain employment within the following month, and 30% remain unemployed. Meanwhile, 80% of those currently employed maintain employment through the following month, and 20% become unemployed. Suppose 75% of the population is currently employed. Using the probabilities and states given, what percentage of the population will likely be employed two months from now? (Enter numerical value only. Do not enter % sign. Round the percentage to 1 decimal place, or to the nearest tenth of a percent.)
The Two-Way table below represents 2 bags of M&Ms. One bag id the peanut M&Ms and the other is the Milk Chocolate (without peanuts) M&Ms. Ms. Bradley pours both bags into a glass jar.

After each selection the M&Ms are not placed back into the jar.
There are three kinds of vegetation in an ecosystem: grass (G), shrubs (S), and trees (T) (Bodine, Lenhart, and Gross 2014). Every year, 25% of grassland plots are converted to shrubs, 20% of shrub plots are converted to trees, 8% of trees are converted to shrubs, and 1% of trees are converted to grass; the other transition probabilities are 0. Calculate the probability of a plot of land have the following succession of vegetation from year to year: GSGG, taking the first state as given. (type three digits after the decimal).
The following equally likely outcomes have been estimated for the returns on Portfolio G and Portfolio H: Scenario Portfolio G Portfolio H 1 5.0% 9.0% 2 3.0% -7.0% 3 9.0% 15.0% 4 9.0% -4.0% Which of the two portfolios is riskier? a. Portfolio H since it has the possibility of a negative return b. Portfolio G since it has the higher expected return c. Both portfolios are equally risky since the possible returns of each are equally likely to occur d. Portfolio H since its returns are more widely dispersed around the expected…

In the current first-year class of a community college, all the students come from three local high schools. Schools I, II, and III supply respectively 30%, 40%, and 30% of the students. The failure rate of students is 4%, 3%, and 6%, respectively. Given that a student passes, what is the probability that he or she came from school I?
