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

A binary number is to be transformed by appending three 0s to the end of the number. For example, 11101 is transformed to 111010
nata0808 [166]

Numbers can be converted from one base to another base. a. The transformed number is 8 times the value of the original number.

Given that:

Three 0s are appended to a binary digit to get a new binary digit.

Using the given values, the transformation can be illustrated as follows:

Where:

represents the three appended 0s.

In binary  represents 8 in decimal.

So, the above illustration can be expressed as:

This means that the new or transformed number is 8 times the original number.
