The probabilities of getting $0,1,2$, or 3 heads in three flips of a balanced coin are, respectively, $\frac{1}{8}, \frac{3}{8}, \frac{3}{8}$, and $\frac{1}{8}$.
Use the formulas that define $\mu$ and $\sigma^{2}$ to find the mean and the standard deviation of this probability distribution. If necessary, round to the nearest thousandth.
