- Parent Volunteer Laurie was completing the treasurer’s report for her son’s Boy Scout troop at the end of the school year. She didn’t remember how many boys had paid the $24 full-year registration fee and how many had paid a $16 partial-year fee. She knew that the number of boys who paid for a full-year was ten more than the number who paid for a partial-year. If $400 was collected for all the registrations, how many boys had paid the full-year fee and how many had paid the partial-year fee?arrow_forwardLaurie was completing the treasurer’s report for her son’s Boy Scout troop at the end of the school year.

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 are 30% 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 that the 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 branches labeled, respectively, O late, 1 late, and 2 late.] (Round your answers to four decimal places.) airline #1 airline #2 airline #3arrow_forward
- The Fresh Oven Bakery sells the pies for $3 each. She knows that the number of pies it can sell varies from day to day. The owner believes that on 50% of the days she sells 100 pies. On another 25% of the days she sells 150 pies, and she sells 200 pies on the remaining 25% of the days. Each day, the owner bakes 200 pies at a cost of $2.50 each. Assume any pies that go unsold are thrown out at the end of the day, find the probability distribution for her daily profit.

Customers get to spin the wheel and, when the wheel stops, a pointer indicates how much they will save. The wheel can stop in any one of 50 sections. Of the sections, 10 produce 0% off, 20 sections are for 10% off, 10 sections for 20%, 5 for 30%, 3 for 40%, 1 for 50%, and 1 for 100% off. Assuming that all 50 sections are equally likely, a. What is the probability that a customer's purchase will be free (100% off)? b. What is the probability that a customer will get no savings from the wheel (0% off)? c. What is the probability that a customer will get at least 20% off?arrow_forward
