Chapter 3: Q12E (page 169)

Male nannies. In a survey conducted by the International Nanny Association (INA) and reported on the INA Web site (www.nanny.org), 4,176 nannies were placed in a job in a given year. Only 24 of the nannies placed were men. Find the probability that a randomly selected nanny placed during the last year is a male nanny (a 鈥渕annie鈥�).

Short Answer

Expert verified

The probability that a randomly selected nanny is a male nanny is 0.0057.

Step by step solution

01

Step-by-Step SolutionStep 1: Probability

Probability refers to the chance of something happening. It is a mathematical branch that studies the occurrence of a random event. The value is given as a number ranging from 0 to 1. Probability has been created to forecast how probable occurrences are to occur. Probability relates to how something is likely to occur.

02

Identify the probability of a male nanny

Given that,

Total number of nannies = 4,176

Number of male nannies = 24

P(malenanny)=TotalnumberofnanniesNumberofmalenanny=244,176=0.0057

Hence, the probability that a randomly selected nanny is a male nanny is0.0057.

b.P(A鈭�C)

c. P (A/B)

e. Are B and C independent events? Explain.

Speeding linked to fatal car crashes. According to the National Highway Traffic and Safety Administration鈥檚 National Center for Statistics and Analysis (NCSA), 鈥淪peeding is one of the most prevalent factors contributing to fatal traffic crashes鈥� (NHTSA Technical Report, August 2005). The probability that speeding is a cause of a fatal crash is .3. Furthermore, the probability that speeding and missing a curve are causes of a fatal crash is .12. Given speeding is a cause of a fatal crash, what is the probability that the crash occurred on a curve?

Jai-alai bets. The Quinella bet at the paramutual game of jai-alai consists of picking the jai-alai players that will place first and second in a game irrespective of order. In jai-alai, eight players (numbered 1, 2, 3, . . . , 8) compete in every game.

a. How many different Quinella bets are possible?

b. Suppose you bet the Quinella combination of 2鈥�7. If the players are of equal ability, what is the probability that you win the bet?

Confidence of feedback information for improving quality. In the semiconductor manufacturing industry, a key to improved quality is having confidence in the feedback generated by production equipment. A study of the confidence level of feedback information was published in Engineering Applications of Artificial Intelligence(Vol. 26, 2013). At any point in time during the production process, a report can be generated. The report is classified as either 鈥淥K鈥� or 鈥渘ot OK.鈥� Let Arepresent the event that an 鈥淥K鈥� report is generated in any time period (t).Let Brepresent the event that an 鈥淥K鈥� report is generated in the next time period. Consider the following probabilities:

P(A)=0.8,PBA=0.9, andPBAC=0.5.

a. Express the event B|Ain the words of the problem.

b. Express the event B|ACin the words of the problem.

c. FindP(AC).

d. FindP(A鈭�B).

e. FindP(AC鈭�B).

f. Use the probabilities, parts d and e, to find P(B).

g. Use Bayes鈥� Rule to find P(A|B), i.e., the probability that an 鈥淥K鈥� report was generated in one time period(t), given that an 鈥淥K鈥� report is generated in the next time period(t+1).

Consider two events A and B, withP(A)=.1,P(B)=.2,andP(A鈭�B)=0

a.Are A and B mutually exclusive?

b.Are A and B independent?
