It was a miscalculation, which must have been revised, probably after others pointed out the same error to himQuote from acrary:
It's probably a typo. I have the 1994 revised edition with the roulette example on pp 36-37. The correct house edge of 5.26 cents per spin is listed.
(Funny that it should appear on pages 36-37, when the equation involved is 36-38
)
