Chapter 3: Q. 21 (page 216)

What is the probability of rolling a prime number of dots with a fair, six-sided die numbered one through six?

Short Answer

Expert verified

The solution isP(prime number)=36=12=0.5

Step by step solution

01

Given

We must determine the probability of rolling a prime number of dots with a fair, six-sided die numbered one through six in the following question.

02

Concept used

Theprobabilityiscalculatedusingthefollowingformula:

Probability =Fawrable number of casesTotal number of cases

For example, if we flip a coin two times, the sample space associated with this random experiment is {HH,HT,TH,TT]where T tails and H heads. Let's suppose A getting one tail. There are two outcomes which favors the event A

localid="1648043311671" [HT,TH},soP(A)=24=0.5.

03

Calculation

We know that while rolling a fair die, there are six possible results. The following are the probable outcomes: {1,2,3,4,5,6}
As a result, the favorable number of instances for rolling a prime number is 3{2,3,5}, and the overall number of cases is 6.
As a result, P(primenumber)=36=12=0.5is the probability of rolling a prime number of dots with a fair, six-sided die.

Roll a fair, six-sided die. Let A = a prime number of dots is rolled. Let B = an odd number of dots is rolled. Then A = {2, 3, 5} and B = {1, 3, 5}. Therefore, A AND B = {3, 5}. A OR B = {1, 2, 3, 5}. The sample space for rolling a fair die is S = {1, 2, 3, 4, 5, 6}. Draw a Venn diagram representing this situation.

What is the sum of the probabilities of an event and its complement?

You have a fair, well-shuffled deck of 52 cards. It consists of four suits. The suits are clubs, diamonds, hearts and spades. There are 13 cards in each suit consisting of 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, J (jack), Q (queen), K (king) of that suit. Three cards are picked at random.

a. Suppose you know that the picked cards are Q of spades, K of hearts and Q of spades. Can you decide if the sampling was with or without replacement?

b. Suppose you know that the picked cards are Q of spades, K of hearts, and J of spades. Can you decide if the sampling was with or without replacement?

Use the The graph shown is based on more than170,000interviews done by Gallup that took place from January through December 2012. The sample consists of employed Americans 18 years of age or older. The Emotional Health Index Scores are the sample space. We randomly sample one Emotional Health Index Score.

Find the probability that an Emotional Health Index Score is 82.7
