Chapter 4: Q2 (page 174)

New Jersey Pick 6 In the New Jersey Pick 6 lottery game, a bettor selects six different numbers, each between 1 and 49. Winning the top prize requires that the selected numbers match those that are drawn, but the order does not matter. Do calculations for winning this lottery involve permutations or combinations? Why?

Short Answer

Expert verified

The calculation for winning the lottery involves combinations, as the order of the numbers does not matter.

Step by step solution

01

Given information

Six different numbers from 1 to 49 are selected in any order.

The lottery is won if the selected numbers match the numbers drawn, and order does not matter.

02

Differentiate between combination and permutation

Combination: The formula of combination is applied if only a certain number of items are to be selected from a pool without replacementsuch that order does not matter.

Permutation: The formula of permutation is applied if a certain number of items are to be selected from a pool without replacementsuch that order matters.

03

Identification for the given problem

It is given that six numbers are selected from 1 to 49 in any order and are then matched with the numbers of the lottery ticket.

As the order does not matter, the calculations involve combinations.

Most popular questions from this chapter

In Exercises 25–32, find the probability and answer the questions. YSORT Gender Selection MicroSort’s YSORT gender selection technique is designed to increase the likelihood that a baby will be a boy. At one point before clinical trials of the YSORT gender selection technique were discontinued, 291 births consisted of 239 baby boys and 52 baby girls (based on data from the Genetics & IVF Institute). Based on these results, what is the probability of a boy born to a couple using MicroSort’s YSORT method? Does it appear that the technique is effective in increasing the likelihood that a baby will be a boy?

Redundancy in Stadium Generators Large stadiums rely on backup generators to provide electricity in the event of a power failure. Assume that emergency backup generators fail 22% of the times when they are needed (based on data from Arshad Mansoor, senior vice president with the Electric Power Research Institute). A stadium has three backup generators so that power is available if at least one of them works in a power failure. Find the probability of having at least one of the backup generators working given that a power failure has occurred. Does the result appear to be adequate for the stadium’s needs?

In Exercises 13–20, express the indicated degree of likelihood as a probability value between 0 and 1.

SAT Test When making a random guess for an answer to a multiple-choice question on an SAT test, the possible answers are a, b, c, d, e, so there is 1 chance in 5 of being correct.

In Exercises 25–32, find the probability and answer the questions.. Guessing Birthdays On their first date, Kelly asks Mike to guess the date of her birth, not including the year.

a. What is the probability that Mike will guess correctly? (Ignore leap years.)

b. Would it be unlikely for him to guess correctly on his first try?

c. If you were Kelly, and Mike did guess correctly on his first try, would you believe his claim that he made a lucky guess, or would you be convinced that he already knew when you were born?

d. If Kelly asks Mike to guess her age, and Mike’s guess is too high by 15 years, what is the probability that Mike and Kelly will have a second date?

In Exercises 13–20, express the indicated degree of likelihood as a probability value between 0 and 1.

Job Applicant Mistakes Based on an Adecco survey of hiring managers who were asked to identify the biggest mistakes that job candidates make during an interview, there is a 50–50 chance that they will identify “inappropriate attire.”
