Chapter 5: Q .79. (page 296)

Box of chocolates According to Forrest Gump, 鈥淟ife is like a box of chocolates. You never know what you鈥檙e gonna get.鈥� Suppose a candymaker offers a special 鈥淕ump box鈥� with 20 chocolate candies that look alike. In fact, 14 of the candies have soft centers and 6 have hard centers. Suppose you choose 3 of the candies from a Gump box at random. Find the probability that all three candies have soft centers

Short Answer

Expert verified

The probability is 0.319.

Step by step solution

01

Step 1:Given information

Number of chocolate candies that look same=20

Number of candies that have soft corner =14

Number of candies that have hard corner=6

02

Step 2:Calculation

The probability that all three randomly selected candies have soft centres can be calculated as:

P(All three have soft centers)=C314C320

=14!(14-3)!脳3!20!(20-3)!脳3!

=3641140

=0.319

Thus, the required probability is 0.319.

Gender and political party In January2017, 52%of U.S. senators were Republicans and

the rest were Democrats or Independents. Twenty-one percent of the senators were

females, and 47%of the senators were male Republicans. Suppose we select one of these

senators at random. Define events R: is a Republican and M: is male.

a. Find P(R 鈭� M). Interpret this value in context.

b. Consider the event that the randomly selected senator is a female Democrat or

Independent. Write this event in symbolic form and find its probability.

Free-throw practice At the end of basketball practice, each player on the team must shoot free throws until he makes 10of them. Dwayne is a 70%free-throw shooter. That is, his probability of making any free throw is 0.70. We want to design a simulation to estimate the probability that Dwayne make10 free throws in at most 12shots. Describe how you would use each of the following chance devices to perform one trial of the simulation.

a. Slips of paper

b. Random digits table

c. Random number generator

Reading the paper In a large business hotel, 40% of guests read the Los Angeles Times. Only 25% read the Wall Street Journal. Five percent of guests read both papers. Suppose we select a hotel guest at random and record which of the two papers the person reads, if either. What鈥檚 the probability that the person reads the Los Angeles Times or the Wall Street Journal?

a. Make a Venn diagram to display the outcomes of this chance process using events L:reads the Los Angeles Times and W: reads the Wall Street Journal.

b. Find PLC鈭�W.

Colorful disksA jar contains 36disks: 9each of four colors鈥攔ed, green, blue, and Page Number: 328yellow. Each set of disks of the same color is numbered from 1to 9. Suppose you draw one disk at random from the jar. Define events R: get a red disk, and N: get a disk with the number 9.

a. Make a two-way table that describes the sample space in terms of events Rand N.

b. Find P(R)and P(N).

c. Describe the event 鈥�Rand N鈥� in words. Then find the probability of this event.

d. Explain why P(RorN)鈮�P(R)+P(N) Then use the general addition rule to computeP(RorN).

Who鈥檚 paying? Abigail, Bobby, Carlos, DeAnna, and Emily go to the bagel shop for lunch every Thursday. Each time, they randomly pick 2of the group to pay for lunch by drawing names from a hat.

a. Give a probability model for this chance process.

b. Find the probability that Carlos or DeAnna (or both) ends up paying for lunch.
