Chapter 5: Q. 102. (page 337)

Matching suits A standard deck of playing cards consists of 52 cards with 13 cards in each of four suits: spades, diamonds, clubs, and hearts. Suppose you shuffle the deck thoroughly and deal 5 cards face-up onto a table.

a. What is the probability of dealing five spades in a row?

b. Find the probability that all 5 cards on the table have the same suit.

Short Answer

Expert verified

The required answers are:

Part a) The probability is 0.0004952.

Part b) The probability is0.001981.

Step by step solution

01

Part a) Step 1: Given information

Given that,

Number of cards in a deck =52

Number of cards in each suit=13

02

Part a) Step 2: Calculation

The probability of taking five spades can be calculated using the following formula:

P(fivespades)=1352脳1251脳1150脳1049脳948=154440311875200=0.0004952

Therefore, the required probability is0.0004952

03

Part b) Step 1: Explanation

The likelihood of all five cards being of the same suit can be calculated as follows:

P(sameunits)=p(5spades)+P(5hearts)+P(5diamonds)+P(5clubs)=3366640+3366640+3366640+3366640=0.001981

Therefore, the required probability is0.001981.

Does the new hire use drugs? Many employers require prospective employees to

take a drug test. A positive result on this test suggests that the prospective employee uses

illegal drugs. However, not all people who test positive use illegal drugs. The test result

could be a false positive. A negative test result could be a false negative if the person

really does use illegal drugs. Suppose that 4%of prospective employees use drugs and

that the drug test has a false positive rate of 5%and a false negative rate of10%.

Imagine choosing a prospective employee at random.

a. Draw a tree diagram to model this chance process.

b. Find the probability that the drug test result is positive.

c. If the prospective employee鈥檚 drug test result is positive, find the probability that she

or he uses illegal drugs.

In an effort to find the source of an outbreak of food poisoning at a conference, a team of medical detectives carried out a study. They examined all 50 people who had food poisoning and a random sample of 200 people attending the conference who didn鈥檛 get food poisoning. The detectives found that 40% of the people with food poisoning went to a cocktail party on the second night of the conference, while only 10% of the people in the random sample attended the same party. Which of the following statements is appropriate for describing the 40% of people who went to the party? (Let F = got food poisoning and A = attended party.)

a. P(F|A) = 0.40

b. P(A|FC) = 0.40

c. P(F|AC) = 0.40

d. P(AC|F) = 0.40

e. P(A|F) = 0.40

Education among young adults Choose a young adult (aged 25to 29) at random. The probability is 0.13that the person chosen did not complete high school, 0.29that the person has a high school diploma but no further education, and 0.30that the person has at least a bachelor鈥檚 degree.

a. What must be the probability that a randomly chosen young adult has some education beyond high school but does not have a bachelor鈥檚 degree? Why?

b. Find the probability that the young adult completed high school. Which probability rule did you use to find the answer?

c. Find the probability that the young adult has further education beyond high school. Which probability rule did you use to find the answer?
