Chance of an Avon sale.The probability that an Avon salesperson sells beauty products to a prospective customer on the first visit to the customer is .4. If the salesperson fails to make the sale on the first visit, the probability that the sale will be made on the second visit is .65. The salesperson never visits a prospective customer more than twice. What is the probability that the salesperson will make a sale to a particular customer?

Short Answer

Expert verified

The probability that the salesperson will make a sale to a particular customer is 0.79.

Step by step solution

01

Important formula

The formula for probability isP=FavourableoutcomesTotaloutcomes

02

Find the probability that the salesperson will make a sale to a particular customer

Here, the probability that an Avon salesperson sells beauty products to a prospective customer on the first visit to the customer is=P(S)=0.4

If the distributor does not sell upon that second appointment P(D|SC)=0.65.

Now,

P(SC)=1鈭�0.4=0.6

Now, the required probability is:

P(T)=P(S)+P(SC).P(D|SC)=0.4+(0.6)(0.65)=0.79

Therefore, the probability that the salesperson will make a sale to a particular customer is 0.79.

Ranking razor blades.The corporations in the highly competitive razor blade industry do a tremendous amount of advertising each year. Corporation G gave a supply of three top-name brands, G, S, and W, to a consumer and asked her to use them and rank them in order of preference.

The corporation was, of course, hoping the consumer would prefer its brand and rank it first, thereby giving them some material for a consumer interview advertising campaign. If the consumer did not prefer one blade over any other but was still required to rank the blades, what is the probability that

a.The consumer ranked brand G first?

b.The consumer ranked brand G last?

c.The consumer ranked brand G last and brand W second?

d.The consumer ranked brand W first, brand G second, and brand S third?

Study of why EMS workers leave the job.Refer to the Journal of Allied Health(Fall 2011) study of why emergencymedical service (EMS) workers leave the profession,Exercise 3.45 (p. 182). Recall that in a sample of 244former EMS workers, 127 were fully compensated whileon the job, 45 were partially compensated, and 72 hadnon-compensated volunteer positions. Also, the numbersof EMS workers who left because of retirement were 7 forfully compensated workers, 11 for partially compensatedworkers, and 10 for no compensated volunteers.

a.Given that the former EMS worker was fully compensatedwhile on the job, estimate the probability that theworker left the EMS profession due to retirement.

b.Given that the former EMS worker had a non-compensatedvolunteer position, estimate the probabilitythat the worker left the EMS profession due toretirement.

c.Are the events {a former EMS worker was fully compensatedon the job} and {a former EMS worker left thejob due to retirement} independent? Explain.

Workers鈥� unscheduled absence survey. Each year CCH, Inc., a firm that provides human resources and employment law information, conducts a survey on absenteeism in the workplace. The latest CCH Unscheduled Absence Surveyfound that of all unscheduled work absences, 34% are due to 鈥減ersonal illness,鈥� 22% for 鈥渇amily issues,鈥� 18% for 鈥減ersonal needs,鈥� 13% for 鈥渆ntitlement mentality,鈥� and 13% due to 鈥渟tress.鈥� Consider a randomly selected employee who has an unscheduled work absence.

a. List the sample points for this experiment.

b. Assign reasonable probabilities to the sample points.

c. What is the probability that the absence is due to something other than 鈥減ersonal illness鈥�?

New car crash tests.Refer to the National Highway TrafficSafety Administration (NHTSA) crash tests of new car models, Exercise 2.153 (p. 143). Recall that the NHTSA has developed a 鈥渟tar鈥� scoring system, with results ranging from one star (*) to five stars (). The more stars in the rating, the better the level of crash protection in a head-on collision. A summary of the driver-side star ratings for 98 cars is reproduced in the accompanying Minitab

Printout. Assume that one of the 98 cars is selected at random. State whether each of the following is true or false.

a.The probability that the car has a rating of two stars is 4.

b.The probability that the car has a rating of four or five stars is .7857.

c.The probability that the car has a rating of one star is 0.

d.The car has a better chance of having a two-star rating than of having a five-star rating.

Shopping with a smartphone.Each year, United Parcel Service (UPS) commissions a 鈥淧ulse of the Online Shopper鈥� survey. The 2015 survey included a sample of 5,118 U.S. shoppers who have made at least two online purchases

every three months. The survey revealed that 41% of the shoppers used a smartphone to make a purchase. Of those who made a smartphone purchase, 38% indicated that they preferred the mobile Web site to the full Web site accessed through a computer. Assume these percentages represent actual probabilities for the population of online shoppers. What is the probability that a randomly selected online shopper uses a smartphone to make a purchase and

prefers the mobile Web site?
