Morning All?

If I have a slot machine with a house edge (e.g. 3%) and I know its low variance, how would I go about calculating the standard deviation?

Standard deviation is the square root of variance.

Although this is true I usually figure this is a purposefully unhelpful response, sort of tongue-in-cheek. It makes *me* laugh anyway. Am I all wet?

Usually the SD can be looked up for games, or you can find the variance [in which case the above is relevant], or you can guess about it from a similar game. see link for VP.
