Bot a spinner with equally sized sections is shown. Z in the top left, W in the top right, Y in the bottom left, X in the bottom right. The spinner arrow is spun once. What number of outcomes make up the sample space?

In this case, the spinner has 4 equally sized sections, so each section represents one outcome. When the spinner is spun once, the arrow can point to any of the 4 sections. Therefore, there are 4 possible outcomes that make up the sample space.
