Use the following information to answer the next 12exercises. The graph shown is based on more than localid="1648902668215">170,000interviews done by Gallup that took place from January through December 2012. The sample consists of employed Americans 18years of age or older. The Emotional Health Index Scores are the sample space. We randomly sample one Emotional Health Index Score.

If we know an Emotional Health Index Score is 81.5 or more, what is the probability that it is 82.7.

Short Answer

Expert verified

The probability of emotional health index score when it is82.7is,PA=0.286.

Step by step solution

01

Given information

Given the Emotional Health Index Score

The emotional health index score 81.5.

When the emotional health index score 82.7, what is the probability.

02

Explanation

The probability of emotional health index score is,

Let the emotional health index score when it is 82.7 be A

P(A)=82.7+82.7(81.5+81.7+81.8+82.3+82.7+82.7+83.7)P(A)=165.4576.4=0.286

Conclusion :

Thus, the probability of emotional health index score when it is 82.7is,P(A)=0.286.

Use the following information to answer the next three exercises. The casino game, roulette, allows the gambler to bet on the probability of a ball, which spins in the roulette wheel, landing on a particular color, number, or range of numbers. The table used to place bets contains of 38numbers, and each number is assigned to a color and a range.

Compute the probability of winning the following types of bets:

a. Betting on two lines that touch each other on the table as in 1-2-3-4-5-6

b. Betting on three numbers in a line, as in 1-2-3

c. Betting on one number

d. Betting on four numbers that touch each other to form a square, as in 10-11-13-14

e. Betting on two numbers that touch each other on the table, as in 10-11or10-13

f. Betting on 0-00-1-2-3

g. Betting on 0-1-2;or0-00-2;or00-2-3

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

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?

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.
