Final answer:
The probability that the spinner stops on a yellow slice is 1 or 100%, because all 8 slices are yellow.
Step-by-step explanation:
The question asks about the probability that a spinner with 8 equally sized yellow slices will stop on a yellow slice when spun. Since all the slices are yellow, the spinner will always stop on a yellow slice.
Thus, the probability of stopping on a yellow slice is 1 or 100%, as there are no other colors present on the spinner to consider.
Probability is a measure of the likelihood that an event will occur, and in this case, since the event is certain to happen (the spinner stopping on a yellow slice), the probability is the highest possible value.
