Answer
Explanation:
Step1: Calculate total number of finger - boards
$9 + 4+3=16$
Step2: Calculate probability of choosing a white finger - board
The number of white finger - boards is 4. The probability $P$ of choosing a white finger - board is $P=\frac{4}{16}=\frac{1}{4}$ Since $\frac{1}{4}<\frac{1}{2}$, and $\frac{1}{4}$ is between 0 and $\frac{1}{2}$, it is closer to 0.
