X=14
2x=28
4x-9=47
you solve for x after you add all the sides

Answer:

Step-by-step explanation:
Given
 i.e. 10 people
 i.e. 10 people
Required
Probability of being next to each other
First, we calculate the total possible arrangements (without any restriction)


If the three are to be next to each other,
First, we arrange the three

Now, the 3 will be seen as 1; so, we have a total of 8 people i.e. (1 + 7 others)
The arrangement is:

So, the total arrangement, when they have to be next to one another is:


The probability is:

Express as percentage
