Using the Fundamental Counting Theorem, it is found that you have 16 choices in building your bike.
It is a theorem that states that if there are n things, each with [tex]n_1, n_2, \cdots, n_n[/tex] ways to be done, each thing independent of the other, the number of ways they can be done is:
[tex]N = n_1 \times n_2 \times \cdots \times n_n[/tex]
In this problem:
Thus, the total number of choices is given by:
N = 4 x 2 x 2 = 16.
