ANSWER:
32 spins
STEP-BY-STEP EXPLANATION:
Since each section has the same size, we can say that the probability that it lands on the number 2 is then 1 in 4 spins.
Now it has to fall a total of 8 times in 2, we can calculate it by means of the following proportion:
[tex]\begin{gathered} \frac{1}{4}=\frac{8}{x} \\ \\ \text{ we solve for x} \\ \\ x=8\cdot4 \\ \\ \\ x=32 \end{gathered}[/tex]
That means it must spin 32 times before the number 2 appears 8 times.
