Final answer:
To calculate the probability of a spinner landing on a particular color, divide the number of sections with that color by the total number of sections on the spinner. The exact probability for the question asked cannot be determined without more details on the spinner's sections and colors.
Step-by-step explanation:
Unfortunately, you have not provided the exact details of the spinner's sections or colors, which is necessary to accurately calculate the probability of landing on black. However, I can explain to you how to calculate such probabilities with an example spinner. Let's say a spinner is divided equally into four sections and two of those are black, one is white, and one is speckled. In this scenario, the probability of landing on black would be the number of black sections divided by the total number of sections.
Since there are two black sections out of a total of four, the calculation to find the probability is 2/4, which simplifies to 1/2. Therefore, the probability of landing on black would be option A. 1/2. Remember that every unique spinner may have a different distribution of colors and numbers of sections, so you'll need to adjust the calculation based on your spinner's specific design.
