A the probability that all children are boys =3÷3 =1
same answer with the girl children
Answer:
A) 1/8 or 0.125 for three girls and three boys
B) 3/8 or 0.375 for two girls and one boy
C) 3/8 or 0.375 for two boys and one girl
D) 1/2 or 0.50, explanation provided below
Step-by-step explanation:
Part A) If a family has three children, the probability that all three children are girls can be found by first finding the probability of one child being a girl. The probability of being a girl in this case is 1/2. The probability of three girls is thus (1/2) * (1/2) * (1/2) = 1/8 or 0.125. The probability of one child being a boy is 1/2, and so rather than repeating the above steps, we can simply say that it is also 1/8 or 0.125.
Part B) For this part, it is probably easiest to list the combinations:
BBB
BBG
BGB
BGG
GBB
GBG
GGB
GGG
There are three outcomes with two girls and one boy and thus the probability is 3/8.
Part C) Looking at the combinations above, we also see that there are three outcomes with two boys and one girl, and thus the probability is 3/8.
Part D) The fact that Josh has a younger brother does not affect the probability that the third child will be a girl or boy. The probability of the third child being a boy is still 1/2.
What is the area and circumference of the circle (3.14 for pi)
We will use the proper formula and solve.
-> A diameter of 48 / 2 = 24 feet as our radius
Area:
A = πr²
A = (3.14)(24)²
A = 1,808.64 ft²
The circle has an area of about 1,808.64 ft²
Circumference:
C = 2πr
C = 2(3.14)(24)
C = 150.72 ft
The circle has a circumference of about 150.72 ft
Answer:
Circumference = 150.72
Area = 1808.64

Answer:
I believe the answer is C) 200.
Step-by-step explanation:
It states that Robin did 2/3 and Rhonda. Rhonda made $195 so we time 2/3 of what Rhonda does to get Robin's pay. Then find out how much he made from the total profit he made $195 * 2/3 = $130. Robin's $130 profit made. Divide that by how much each. $130 / $0.65 = 200. Robin assemble 200.
Answer:
C)200
Step-by-step explanation:
divide 195 by .65
whats 2/3 or 300
your answer should be 200

What is the interquartile range of this data set?
{18, 17, 10, 25, 20, 20, 30, 18, 18, 30, 25}
Enter the answer in the box.
The interquartile range of the data set is 7.
Step-by-step explanation:
The given set of data is {18 , 17 , 10 , 25 , 20 , 20 , 30 , 18 , 18 , 30 , 25}
Arrange the data in ascending order:
10 , 17 , 18 , 18 , 18 , 20 , 20 , 25 , 25 , 30 , 30
Divide the data in two equal parts:
(10 , 17 , 18 , 18 , 18), 20 ,(20 , 25 , 25 , 30 , 30)
Divide each parenthesis in 2 equal parts:
(10 , 17), 18 ,(18 , 18), 20 ,(20 , 25), 25 ,(30 , 30)
Now we can say that,
Q₁ = 18 , Median = 20 , Q3 = 25
Interquartile rage of a data is :
I.Q.R. = Q3 - Q1
I.Q.R. = 25-18 = 7
Therefore the interquartile range of the data set is 7.

12. If four coins are flipped, find the probability of obtaining two heads and two tails.
Answer: 1/16 or 0.0625
Step-by-step explanation:
The probability of getting a heads is 1/2, and the probability of getting a tails is 1/2. To find the probability of getting 2 heads and 2 tails, multiply the probabilities of each event together. 1/2 * 1/2 * 1/2 * 1/2 = 1/16.
Josh paid for 5 pounds of grapes with a $10 bill. He got back $7.50. What was the cost of 1 pound of grapes?

Find the areas of the figures below.
Answer:
1. 158 sq units
2. 225 sq meters
3. 303 sq units
Step-by-step explanation:
10x14=140+(6x3)=140+18=158
(7x7)+(16x11)=49+176=225
(9x2)+(15x19)=18+285=303
