Consider a purely probabilistic game that you have the opportunity to play. Each time you play there are n potential outcomes x1, x2, ..., xn (each of which is a specified gain or loss of euros). These outcomes x1, x2, ..., xn occur with the probabilities p1, p2, ..., pn respectively (where p1 + p2 + ... + pn = 1.0 and 0 <= pi <= 1 for each i). Positive xi values mean a gain of |xi| euros and negative values mean a loss of |xi| euros. Assume that x1, x2, ..., xn and p1, p2, ..., pn are all known quantities. Furthermore, assume that each play of the game takes up one hour of your time, and that only you can play the game (you can't hire someone to play for you). Let M be the game's expected value. That is, M = p1*x1 + p2*x2 + ... + pn*xn. Let S be the game's standard deviation. That is, S = SquareRoot( p1 * (x1 - M)^2 + p2 * (x2 - M)^2 + ... + pn * (xn - M)^2 ). Tasha's school bus usually drops her off in town every day at 4pm and her mother picks her up at the bus stop. Last Friday was a short day, only Tasha's mother forgot so she wasn't at the bus stop when Tasha was dropped off an hour early, at 3pm. Since Tasha had forgotten her cell phone at home, she decided to walk home along her mother's driving route. Her mother left home at the usual time and picked Tasha up along the way. They arrived home 10 minutes before their usual arrival time. At what time did Tasha's mother pick her up? Can you determine how far Tasha walked and/or how far her home is from the bus stop?
