Final answer:
Maya can use a spinner divided into 4 equal sections labeled a, b, c, d.
Step-by-step explanation:
Maya can use spinner option 1) A spinner divided into 4 equal sections labeled a, b, c, d. This is because the theoretical probabilities for each section match the probabilities assigned to each section of the spinner. Option 1) has a probability of 1/2 for section a, 1/4 for section b, and 1/4 for section c, which matches the probabilities given.
Option 2) has 4 sections labeled a, which does not match the probabilities. Option 3) has 4 sections, but they are not labeled correctly. Option 4) has 8 sections and the labels do not match the probabilities.
