The Mathematics of Poker

Hey, I'm not sure if this is errata or user-error, but I've been plodding through this book, stopping to make sure I understand each equation and application fully. On page 26, they plug their example game into equation 2.4 to figure the standard deviation for the variance (2.61)

the equation is something like:

STDEV = 2.61 * SQRT 100

and they end up with an answer of 36.89. How? Isn't SQRT(100) = 10? so 2.61 * 10 = 26.1?

Note: I have a BA and clepped out of all my college math, so be gentle if this is a dumb question.

Yes, this equation should say sqrt(200) instead of 100. This and other errata can be found at:

It's really really hard to find all the small errors in a book like this; we had several people all reading the book looking for this type of stuff, but things do slip through the cracks. In future printings the errors that we (or you!) find will be corrected.
