erick has a collection of 8 brown fingerboards, 4 green fingerboards, and 4 silver fingerboards. he chooses one at random. locate the probability of the following events on the number line. a green fingerboard is chosen. a b c d e
Answer
Explanation:
Step1: Calculate total number of finger - boards
$8 + 4+4=16$
Step2: Calculate probability of choosing a green finger - board
The number of green finger - boards is 4. Probability $P=\frac{4}{16}=\frac{1}{4}$
Step3: Locate $\frac{1}{4}$ on the number line
$\frac{1}{4}$ is between 0 and $\frac{1}{2}$. It is closer to 0. Among the points A, B, C, D, E, the point corresponding to $\frac{1}{4}$ is B.
Answer:
B
