A team of 7 is chosen travels to a match in 2 cars. A group of 4 travel in one car and a group of 3 travel in the other car.
In how many different ways can the team of 7 be divided into a group of 4 and a group of 3?

So, you're choosing a group of 4 people from 7 people (and 3 are left over).
7C4, as order doesn't matter.

7C4 = 7!/4!3! = 7*6*5/3*2 = 35

So 35 ways of choosing the first 4, so a total of 35 ways.

(If you do 7C3, you also end up with 35).

So is the answer 35 😃
