a brown, green, or silver fingerboard is chosen.
options: a, b, c, d, e with a number line showing points a (0), b, c (1/2), d, e (1)

Explanation:

Step1: Calculate total fingerboards

Total = 8 + 4 + 4 = 16

Step2: Calculate probability of chosen event

Probability = $\frac{\text{Number of favorable outcomes}}{\text{Total outcomes}} = \frac{8 + 4 + 4}{16} = \frac{16}{16} = 1$

Step3: Locate on number line

The value 1 corresponds to point E.

E
