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
Answer:
f(25/29) =
Step-by-step explanation:
In order to do this problem, we need to plug in for x. When we plug it in we get
. After this we can start by multiplying. When we multiply
we get
. Since the fraction cannot be simplified any further, we can now add 5. In order to add 5 we need to find a common denominator, which in this case will be 29. Changing the denominator to 29 gives us
because when changing the denominator we have to multiply the numerator by the same number. After adding these fractions we get our answer of
.
