The probability for each event follows below:

P(A)= 0.23

P(E)= 0.24

P(F)= 0.28

P(N)= 0.12

P(O)= 0.07

P(S)= 0.06

<h3>Probability</h3>

Probability can be defined as the possibility that an event will occur. For an event, the probability can be found from the ratio between the number of favorable outcomes for the event and the total number of outcomes.  Values of probability vary between 0 and 1.

A probability for an event is represented by P(A), P(B), etc. And exactly this that question asks for you.

1. Arrange the text of the question

       North America=23 countries

       South America= 12 countries

       Europe=  47 countries

       Asia= 44 countries

      Africa =54 countries

      Oceania= 14 countries

2. Find the total of countries

N_{total}=23+12+47+44+54+14=194

3. Find P(A)

A= the event that a country is in Asia= 44 countries. Therefore,

P(A)=\frac{numberofcountries of Asia}{Total number of countries } \\ \\ P(A)=\frac{44}{194} =0.23\\ \\ P(A)=0.23

4. Find P(E)

E= the event that a country is in Europe= 47 countries. Therefore,

P(E)=\frac{numberofcountries of Europe}{Total number of countries } \\ \\ P(E)=\frac{47}{194} =0.24\\ \\ P(E)=0.24

5. Find P(F)

F= the event that a country is in Africa= 54 countries. Therefore,

P(F)=\frac{numberofcountries of Africa}{Total number of countries } \\ \\ P(F)=\frac{54}{194} =0.28\\ \\ P(F)=0.28

6. Find P(N)

N= the event that a country is in North America= 23 countries. Therefore,

P(N)=\frac{numberofcountries of North America}{Total number of countries } \\ \\ P(N)=\frac{23}{194} =0.12\\ \\ P(N)=0.12

7. Find P(O)

O= the event that a country is in Oceania= 14 countries. Therefore,

P(O)=\frac{numberofcountries of Oceania}{Total number of countries } \\ \\ P(O)=\frac{14}{194} =0.07\\ \\ P(O)=0.07

8. Find P(S)

S= the event that a country is in South America= 12 countries. Therefore,

P(S)=\frac{numberofcountries of South America}{Total number of countries } \\ \\ P(S)=\frac{12}{194} =0.06\\ \\ P(S)=0.06

Georgia’s scores in six subjects are 89, 75, 92, 68, 78, 75, and 80. If she finds a single value that summarizes all the values
Allushta [10]
Hey there! :)

Your answer is mean
_____________________________________________________________

Mean is the average value of the data set.
Mode is the number that appears the most
Range is the difference between the greatest value and the lowest value in a data set.

Finding the mode is pretty useless because you can't do much with the score that you got the most.

Range isn't that helpful because it's the difference between your best and worst score.

Mean is best for summarizing because you have 1 number that's the average of the whole data set.
______________________________________________________________

Therefore, the answer is mean

Hope this helps :)

Express $8\sqrt{18}$ in the form $a\sqrt b$, where $a$ and $b$ are integers and $b$ is as small as possible.
AnnyKZ [126]

8 √18 = 8 √(9 × 2)

= 8 √(3² × 2)

= 8 √(3²) √2

= (8 × 3) √2

= 24 √2
