Given

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:

Expand

Express as percentage
