Since the order of selection does not matter we will use combinations to solve this problem.

Total number of students = 20
Number of students to be selected = 4

We are to find the combinations of 20 objects taken 4 at a time. This can be expressed as 20C4

How many different 4 color code stripes can be made on a sports car if each code consists of the colors green, red, blue, and wh
Akimi4 [234]
From the list of colors: green, red, blue, and white, there are four colors. The concept that should be used in order to determine the number of 4-color code stripes that can be drawn in the sports car is the concept of BASIC PRINCIPLE OF COUNTING.

The equations that would best help us in answering the question is,
                         n = 4! (that is, four factorial)
For the first pick, there are four choices. When one is already used then, there are only 3 choices for the second color, and so on until the last color. 
                         n = 4 x 3 x 2 x 1 = 24
Thus, there are 24 types of 4-color codes.
