Answer

Explanation:

Step1: Calculate total number of finger - boards

Total = 9 + 4+ 3=16

Step2: Calculate probability of choosing a white finger - board

$P(\text{white})=\frac{4}{16}=\frac{1}{4}$ Since $\frac{1}{4}$ is between 0 and $\frac{1}{2}$, it corresponds to point B on the number - line.

Step3: Calculate probability of choosing a black finger - board

There are 0 black finger - boards. So $P(\text{black}) = 0$, which corresponds to point A on the number - line.

Answer:

A white finger - board: B A black finger - board: A
