A circular spinner is divided into four regions labeled $A$, $B_1$, $B_2$, and $C$. The probability of the spinner stopping on region $A$ is $\frac{3}{8}$. The regions labeled $B_1$ and $B_2$ are sub-regions of $B$, where the probability of stopping on $B_1$ is $\frac{1}{8}$ and on $B_2$ is $\frac{1}{4}$. Determine the probability of the spinner stopping on region $C$.
