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,

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