x P(X)
0 0.238

2 0.269
3 0.055

There is 70.7% chance that at least one but at most two adults in the sample believes in the ghost
12.
1.14≅1
There will be one adult out of three we expect to believe in the ghost
Step-by-step explanation:
The probability distribution is constructed using binomial distribution.
We have to construct the probability distribution of the number adults believe in ghosts out of three adults. so,
x=0,1,2,3
n=3
p=probability of adults believe in ghosts=0.38
The binomial distribution formula
nCxp^xq^n-x=3cx0.38^x0.62^3-x
is computed for x=0,1,2,3 and the results depicts the probability distribution of the number adults believe in ghosts out of three adults.
x P(X)
0 0.238
1 0.438
2 0.269
3 0.055
11.
P(at least one but at most two adults in the sample believes in the ghost )= P(x=1)+P(x=2)=0.437+0.269=0.707
P(at least one but at most two adults in the sample believes in the ghost )=70.7%
12. E(x)=n*p
here n=3 adults and p=0.38
E(x)=3*0.38=1.14
so we expect one adult out of three will believe in the ghosts.
Answer:
1000 Grams : 1 Kilogram or 1 Kilogram : 1000 Grams
Step-by-step explanation:
In the metric system the value of a kilogram is solved like:

When converting from grams to kilograms, we solve it like:

Let's take for example:
2 KG is how many grams?
We use the grams to kilograms formula like so:

Then we end up with:
g = 2000

Here is the graphical explanation in the annex.
A = (-2; 4)
A' = (-2 - 4; 4 - 2) = (-6; 1)
After reflection on F(X)
<h2>A'' = (-1; 6) </h2>
Answer:
I think that the awnser is A because I think it is
