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.
