The Binomial Coefficient can be used to calculate the number of ways objects can be arranged.
<u>Binomial Coefficient</u>

The exclamation mark "!" placed after a number means factorial and indicates to multiply all whole numbers from the given number down to 1.
Example: 4! = 4 × 3 × 2 × 1
The Binomial Coefficient gives us the number of ways of picking "r" unordered outcomes from "n" possibilities.
As there are 8 friends ⇒ n = 8.
As each car takes 4 friends ⇒ r = 4.
Substitute these values into the formula:

Answer:
Simon takes approximately 13.76 hours to complete the job alone.
Step-by-step explanation:
We are given the following in the question:
Kamila can do a job in 26 hours
So, part of work done by Kamila in 1 hour =

Simon and Kamila working together can do the same job in 9 hours
.
So, (Simon and Kamila)'s 1 hour work =

So, Simon's 1 hour work =

So,
Simon can do
part of work in hour = 1
Time taken by Simon to complete the job alone =

Thus, Simon takes approximately 13.76 hours to complete the job alone.
