You participate in a series of free games where you can place small bets on outcomes and either win, lose, or tie. Each play of the game has 5 possible payouts in dollars, each with equal probability: 0, $\pm 5.0$, $\pm 7.5$ (positive/negative correspond to if you win/lose that amount, 0 if you tie). If you play this game 100 times, what is the SE for the number of times you win? (your answer must be correct to $\pm 0.1$)

4. The residual volume a is the difference between the ideal-gas volume and the actual gas volume. It is defined by the equation $\alpha = \frac{RT}{P} - v$ For a certain gas, $\alpha$ has been measured at 100°C and at different molar volumes; the re- sults are expressed by the empirical equation $\alpha = 2 - (3/v^2)$, where $v$ is in L mol$^{-1}$. The velocity of sound $w$ is given by the formula $w^2 = -g_c k v^2 \left(\frac{\partial P}{\partial v}\right)_T$ where $g_c$ is a dimensional constant equal to 1 kg m N$^{-1}$ s$^{-2}$. Calculate the velocity of sound for this gas at 100°C when its molar volume is 2.3 liter, using $k = 1.4$. The molar mass is 100 g mol$^{-1}$.
