The probability that all three would recommend their attorney to a friend is 18.19%, and the probability that the first would not, but the second and third would recommend their attorney to a friend is 8.56%.
<h3><u>Probabilities</u></h3>
Since the Better Business Bureau conducts a survey of 30 people who recently hired an attorney, and 17 of them say that they would recommend their attorney to a friend, while 8 say that they would not recommend their attorney to a friend, and the remaining 5 say that they are not sure, and then three people are selected from this group of 30 people at random, to determine what is the probability that A) all three would recommend their attorney to a friend, and B) the first would not, but the second and third would recommend their attorney to a friend, the following calculation must be performed:
A)
- 17/30 x 17/30 x 17/30 = X
- 0.5666 x 0.5666 x 0.5666 = X
- 0.1819 = X
B)
- 8/30 x 17/30 x 17/30 = X
- 0.2666 x 0.5666 x 0.5666 = X
- 0.0856 = X
Therefore, the probability that all three would recommend their attorney to a friend is 18.19%, and the probability that the first would not, but the second and third would recommend their attorney to a friend is 8.56%.

Answer:
Can you give more info.?
Step-by-step explanation:
A.
Cars Amount
0 cars $-117.50
1 car $-113.50
2 cars $-109.50
3 cars $-106.50
4 cars $-102.50
10 cars $-77.50
50 cars $82.50
100 cars $282.50
I do not know what graph you have but, you can see how much money you will make because it will form a straight line on the graph. As long as you continue the line, you will be able to see how many cars you have to clean to make a certain amount of money. Same is for the table.
B.
The change in the amount of money earned with each car is $4.00
The change on the graph is shown by the increasing slope.
C.
The number of cars that need to be washed can be seen by using the formula y=4x-117.5
The information from part a and b is used to show that there is a constant change (slope) and that more money is made by washing more cars.
3. The members need to wash 30 cars (rounded up from 29.375) to break even.
4. The members would have to wash 249 cars (rounded from 248.125) to fund their Washington trip.
The members would have to wash 117 cars (116.875) to fund their Valentine's Day Dance.
5. They would have to wash 366 cars.
Realistic
This can be realistic if there are a lot of members in the Math Club and if they set up in a good location. It will be successful.
Not Realistic
This is not realistic because there are many other factors that need to be taken into consideration. There might not be enough cars or people that are willing to get their car cleaned by these students. There are other supplies that they might need to buy and more.
Your answer is correct, your on the right track as well. Just flip the negative number to its respective location.
Good luck :)
