What is the theoretical probability of spinning an even number on a spinner is 23. The spinner has 8 even-number sections. How many sections are on the spinner?

To find the total number of sections on the spinner, we use the theoretical probability formula. If the probability of spinning an even number is ( \frac{23}{x} ) and there are 8 even-number sections, we set up the equation: ( \frac{8}{x} = \frac{23}{1} ). Solving for ( x ) gives ( x = \frac{8 \times 1}{23} ), which implies there are 184 sections on the spinner (since ( x = \frac{8 \times 1}{23} ) leads to ( 8 \times 23 = 184 )). Thus, the spinner has 184 sections in total.
