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.

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 : INFERENTIAL STATISTICS
Step-by-step explanation: Inferential statistics is a statistical inference, where conclusion is drawn using a set of data that are not gotten from the sample study, but are assumed to relate with the sample study. This type of statistics relies on a probability, that the assumed data used to analyze a sample can be used to study the properties of that sample.
