Question

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.1. a green fingerboard is chosen.options: b2. a blue fingerboard is chosen.options: a, b, c, d, e

Explanation:

Step1: Calculate total fingerboards

Total = $8 + 4 + 4 = 16$

Step2: Probability of green fingerboard

Probability = $\frac{\text{Green count}}{\text{Total count}} = \frac{4}{16} = \frac{1}{4}$

Step3: Locate $\frac{1}{4}$ on number line

The number line has 0 at A, $\frac{1}{2}$ at C, 1 at E. $\frac{1}{4}$ is halfway between 0 and $\frac{1}{2}$, which is point B.

Step4: Probability of blue fingerboard

There are 0 blue fingerboards. Probability = $\frac{0}{16} = 0$, which is point A.

Answer:

1. A green fingerboard is chosen: B
2. A blue fingerboard is chosen: A
