Suppose that each child born is equally likely to be a boy or a girl. Consider a family with exactly three children. Let BBG indicate that the first two children born are boys and the third child is a girl, let GBG indicate that the first and third children born are girls and the second is a boy, and so forth. (a) Use set-roster notation to describe the elements in the sample space whose outcomes are all possible genders of the three children. (b) Write each of the following events as a set, in set-roster notation, and find its probability. (i) the event that exactly one child is a girl set probability (ii) the event that at least two children are girls set probability (iii) the event that no child is a girl set probability
Answer:
(a)
[tex]S = \{GGG, GGB, GBG, GBB, BBG, BGB, BGG, BBB\}[/tex]
(b)
i.
[tex]1\ girl = \{GBB, BBG, BGB\}[/tex]
[tex]P(1\ girl) = 0.375[/tex]
ii.
[tex]Atleast\ 2 \ girls = \{GGG, GGB, GBG, BGG\}[/tex]
[tex]P(Atleast\ 2 \ girls) = 0.5[/tex]
iii.
[tex]No\ girl = \{BBB\}[/tex]
[tex]P(No\ girl) = 0.125[/tex]
Step-by-step explanation:
Given
[tex]Children = 3[/tex]
[tex]B = Boys[/tex]
[tex]G = Girls[/tex]
Solving (a): List all possible elements using set-roster notation.
The possible elements are:
[tex]S = \{GGG, GGB, GBG, GBB, BBG, BGB, BGG, BBB\}[/tex]
And the number of elements are:
[tex]n(S) = 8[/tex]
Solving (bi) Exactly 1 girl
From the list of possible elements, we have:
[tex]1\ girl = \{GBB, BBG, BGB\}[/tex]
And the number of the list is;
[tex]n(1\ girl) = 3[/tex]
The probability is calculated as;
[tex]P(1\ girl) = \frac{n(1\ girl)}{n(S)}[/tex]
[tex]P(1\ girl) = \frac{3}{8}[/tex]
[tex]P(1\ girl) = 0.375[/tex]
Solving (bi) At least 2 are girls
From the list of possible elements, we have:
[tex]Atleast\ 2 \ girls = \{GGG, GGB, GBG, BGG\}[/tex]
And the number of the list is;
[tex]n(Atleast\ 2 \ girls) = 4[/tex]
The probability is calculated as;
[tex]P(Atleast\ 2 \ girls) = \frac{n(Atleast\ 2 \ girls)}{n(S)}[/tex]
[tex]P(Atleast\ 2 \ girls) = \frac{4}{8}[/tex]
[tex]P(Atleast\ 2 \ girls) = 0.5[/tex]
Solving (biii) No girl
From the list of possible elements, we have:
[tex]No\ girl = \{BBB\}[/tex]
And the number of the list is;
[tex]n(No\ girl) = 1[/tex]
The probability is calculated as;
[tex]P(No\ girl) = \frac{n(No\ girl)}{n(S)}[/tex]
[tex]P(No\ girl) = \frac{1}{8}[/tex]
[tex]P(No\ girl) = 0.125[/tex]
I am a 2-digit number. If sum of my two digits is added to the product of my digits, it is me again. Can you find me?
Answer:
Step-by-step explanation:
Let “ab” represent the digits of the number.
a ≠ 0
Value of the number = 10a+b
a+b + ab = 10a + b
a + ab = 10a
ab = 9a
b = 9
“ab” = 19, 29, 39, 49, 59, 69, 79, 89, 99
Answer: 49
Step-by-step explanation:
4x9=36
4+9=13
36+13=49

You throw two dice. What is the probability of rolling a sum of 6 given that you rolled a sum that is greater than 4?Ill give BRAINLEST to best answer with explanation
Answer:
8/12
Step-by-step explanation:
if you have 2 dice and roll them t the same time you have 11 possible outcomes. 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12. If you roll something higher then a 4 then you get left with 5, 6, 7, 8, 9, 10, 11, 12. If you count them there is 8 different outcomes you can get out of the 2 dice since the highest you can roll is a 12.
The Patel family looks at a map to plan their family vacation. They plan to travel from Smithville to Jonesville, which are 334 3 3 4 inches apart on the map. Then they plan to travel from Jonesville to Clarksville, which are 514 5 1 4 inches apart on the map. The scale on the map is 12 1 2 inch equals 4 miles. What is the actual distance the Patel family will travel by the time they reach Clarksville?
Answer:
282.63 miles
Step-by-step explanation:
A scale drawing is a reduced form in terms of dimensions of an original image / building / object
the scale drawing is usually reduced at a constant dimension
scale of the drawing = original dimensions / dimensions of the scale drawing
Distance from Smithsville to Clarksville = distance from Smithville to Jonesville + distance from Jonesville to Clarksville
distance from Smithville to Jonesville = (334 x 4) / 12 = 111. 3 miles
distance from Jonesville to Clarksville = (514 x 4) / 12 = 171.33
111.3 + 171.33 = 282.63
A cylinder has a radius of 10 m and a height of 8 m.
What is the exact volume of the cylinder?
A. 187 m
B. 807 m
C. 160 m
D. 800 m
Answer:
D. 800 m
Step-by-step explanation:
Volume of a cylinder is πr²h
Here, r=10 h=8
so the volume is
=π x 10² x8
=π x 100 x 8
=800m
The answer is 800m
Answer:
[tex]D[/tex]
Step-by-step explanation:
[tex]Volume[/tex] [tex]of[/tex] [tex]cylinder[/tex] ≈ [tex]\pi[/tex] [tex]radius^{2}[/tex] × [tex]height[/tex]
[tex]Volume[/tex] ≈ [tex]\pi[/tex] × [tex]10^{2}[/tex] × 8 [tex]800\pi[/tex]

Uno se pierde, el otro se recicla.
Explicación:
El movimiento de nutrientes difiere del flujo de energía en un ecosistema porque los nutrientes se pueden reciclar mientras que, por otro lado, la energía se pierde en el ecosistema. Tanto los nutrientes como la energía fluyen en la misma dirección y toda la energía del ecosistema proviene del sol, que es la principal fuente de energía. Entonces podemos decir que la energía perdida y los nutrientes se reciclan en el ecosistema.

Can someone help me please
Answer:
the answer to this question is 4.4
Answer:
4.4
Step-by-step explanation:
We will use Pythagorean Theorem to find the remaining side.
Since the hypothenuse (10) is already found, we will do this a little more unconventionally.
9²+x²=10²
x Represents the missing side.
81+x²+100
x²=19
x≈ 4.4

The graph below can be used to solve which equation? 1x + 2– 5= -(x - 1)(x - 3) 8 5 x + 2 - 5 = (1 - 1)(x - 3) 3 2 1 2-21-5= -(2+1)(2+3) A 0 5 3 2 1 0 2 7 s 6 2 - 2 - 5 = -(-1)(2-3) 6 My Progress 355
Answer:
B
Step-by-step explanation:
The graph of function is |x + 2| – 5= -(x - 1)(x - 3) which is represented in the graph option first is correct.
What is a function?It is defined as a special type of relationship, and they have a predefined domain and range according to the function every value in the domain is related to exactly one value in the range.
As we can see in the graph, there are two graphs of a function shown.
First one is a graph of a mod function and second one is a graph of a quadratic equation.
|x + 2| – 5= -(x - 1)(x - 3)
f(x) = |x + 2| - 5
g(x) = -(x - 1)(x - 3)
Thus, the graph of function is |x + 2| – 5= -(x - 1)(x - 3) which is represented in the graph option first is correct.

Malcolm is filling bags with rice. He starts with a 5
1 over 4 pound container of rice and fills each
bag with pound of rice. How many bags of rice can Malcolm fill?
(I think that says 51...)
Basically all you do is multiply 51 by 4
51
x 4
104
The answer (if those numbers are correct) is 104.
