Question

david has a collection of 9 gray fingerboards, 4 white fingerboards, and 1 yellow fingerboard. he chooses one at random. 1. write the probability of the following events on the number line. a white fingerboard is chosen. a b c d e

Explanation:

Step1: Calculate total fingerboards

$9 + 4 + 2 = 15$

Step2: Find probability of white

$\text{Probability} = \frac{4}{15} \approx 0.27$

Step3: Match to number line

The number line has A=0, E=1, so intervals are $\frac{1}{4}=0.25$ each. $\frac{4}{15}\approx0.27$ falls in the first interval after 0, which is point B.

Answer:

B
