ANSWER:

32 spins

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:


\begin{gathered} (1)/(4)=(8)/(x) \\ \\ \text{ we solve for x} \\ \\ x=8\cdot4 \\ \\ \\ x=32 \end{gathered}

That means it must spin 32 times before the number 2 appears 8 times.
