QUESTION 3 Let G and H be two events in a sample space. P(G) = 0.4, P(H) = x and P(G or H) = 0.7 3.1 For what value of x are G and H mutually exclusive? (2)
For x = 0.33, the events G and H are mutually exclusive.
Here, we are given that-
P(G) = 0.4
P(H) = x
and P(G or H) = 0.73
⇒ P(G∪H) = 0.73
Now, we know that-
P(G U H) = P(G) + P(H) - P(G ∩ H)
For any two events that are mutually exclusive, the probability that they occur at the same time is 0. Hence, if G and H are mutually exclusive, then P(G ∩ H) will be 0
⇒ 0.73 = 0.4 + x - 0
x = 0.73 - 0.4
x = 0.33
Thus, for x = 0.33, the events G and H are mutually exclusive.

Paul needs to randomly select one of his four children to go first in a board game. Which simulation tools could he use in this situation?
1. a spinner divided evenly into 12 sections, with three sections each of four different colors. - Correct
2. a bag containing 12 chips in two different colors, with six of each color.
3. a standard deck of cards.
4. two coins -Correct
5. a six-sided number cube
Answer:
1/3/4 are all correct
Step-by-step explanation:
For Paul to select 1 of his 4 children, the simulation tool must have the possibility of giving a result of 1/4 (i.e. 1 in 4 children). The simulation tools capable of these results are: (1), (3) and (4)
To determine which simulation tool is correct for the situation, we simply put each option to test.
Option (1)
[tex]Sections = 12[/tex]
[tex]Sub= 3[/tex]
Here, the simulation is done by calculating the probability of each subsection.
The probability is:
[tex]Pr = \frac{Sub}{Sections}[/tex]
[tex]Pr = \frac{3}{12}[/tex]
Simplify
[tex]Pr = \frac{1}{4}[/tex]
Option 2
[tex]Chips =12[/tex]
[tex]Sections = 2[/tex]
Here, the simulation is done by calculating the probability of each section.
The probability is:
[tex]Pr = \frac{Sections}{Chips}[/tex]
[tex]Pr = \frac{2}{12}[/tex]
Simplify
[tex]Pr = \frac{1}{6}[/tex]
Option 3
A standard deck has:
[tex]Cards = 52[/tex]
[tex]Suit = 13[/tex]
Here, the simulation is done by calculating the probability of each suit.
The probability is:
[tex]Pr = \frac{Suits}{Cards}[/tex]
[tex]Pr = \frac{13}{52}[/tex]
Simplify
[tex]Pr = \frac{1}{4}[/tex]
Option 4
[tex]Coins = 2[/tex]
Here, he needs to toss the coin 2 times. So, the possible sample space are:
[tex]S = \{HH, HT, TH, TT\}[/tex]
The probability of one of the outcomes is:
[tex]Pr = \frac{1}{n(S)}[/tex]
Where:
[tex]n(S) = 4[/tex] ---- number of outcomes
So:
[tex]Pr =\frac{1}{4}[/tex]
Option 5:
[tex]Sides =6[/tex]
The probability of getting 1 of the 6 faces is:
[tex]Pr = \frac{1}{6}[/tex]
Paul can only use simulations that give 1/4. Hence, (1), (3) and (4) are correct because they all equal 1/4.

Say you have 47,964 blocks. For every 4 yellow blocks, you have 1 orange block. For every 4 orange blocks, you have 1 red block. For every 2 yellow blocks, you have 3 blue blocks. How many of each color block do you have?
Please show steps I'm horrible at multiple-ratio problems
Using proportions, the amounts you have of each block are given as follows:
Blue: 25,581.Yellow: 17,054Orange: 4,263.Red: 1,066What is a proportion?A proportion is a fraction of a total amount, and the measures are related using a rule of three. Due to this, relations between variables, either direct(when both increase or both decrease) or inverse proportional(when one increases and the other decreases, or vice versa), can be built to find the desired measures in the problem, or equations to find these measures.
From the amounts given, you can create the following ratio:
Blue : Yellow : Orange : Red
6 : 4 : 1 : 0.25.
Hence the fractions corresponding to each color are given as follows:
Blue: 6/(6 + 4 + 1 + 0.25) = 6/11.25.Yellow: 4/11.25.Orange: 1/11.25.Red: 0.25/11.25.Hence the number of blue blocks is found as follows:
6/11.25 x 47964 = 25,581.
The number of yellow blocks is given by:
4/11.25 x 47964 = 17,054.
The number of orange blocks is given by:
1/11.25 x 47964 = 4,263.
The number of red blocks is given by:
0.25/11.25 x 47964 = 1,066.

What is the radius of a hemisphere with a volume of 6466 to the nearest tenth of a meter?
Answer:
14.6m
Step-by-step explanation:

mean=6.4
standard deviation=0.6
we have to find the range in which at least 75% of the data will reside
1-1/k²=0.75
1/k²=1-0.75
1/k²=0.25
k²=1/0.25=4
k=2
so, k=2
The range of values can be computed as mean±k(standard deviation).
Thus, the range in which at least 75% of the data will reside is
(mean-k(standard deviation), mean+ k(standard deviation))

BD bisects angle ABC. Solve for x and find m angle ABC.
m angle ABD = 6x-8, m angle CBD = 3x + 4
Answer:
The value of x = 4
so
m ∠ABD = 6x-8 = 6(4)-8 = 24-8 = 16m∠CBD = 3x+4 = 3(4)+4 = 12+4 = 16Step-by-step explanation:
We know that an angle bisector bisects the angle into two equivalent angles.
When BD bisects angle ABC, it forms two equivalent angles which are:
m∠ABDm∠CBDsuch as
m∠ABD = m∠CBD
as
m ∠ABD = 6x-8
m∠CBD = 3x+4
so the equation becomes
m∠ABD = m∠CBD
6x-8 = 3x+4
6x - 3x = 4 + 8
3x = 12
Divide both sides by 3
x = 4
Thus, the value of x = 4
so
m ∠ABD = 6x-8 = 6(4)-8 = 24-8 = 16m∠CBD = 3x+4 = 3(4)+4 = 12+4 = 16
