If playing the baccarat variant "commission-free baccarat" with a fortune bonus bet that pays 40-1, what is the standard deviation of the bet?

The 40-1 bet I am speaking of is the one that pays only when the bank wins with a 3 card total of 7, if the player beats the bank, the bet does not pay.

Secondarily, if one were to have played say 350-ish hands and not hit a bonus, how "normal" is that?

I get a standard deviation of 6.08.
You have about 1 in 2913 chance of losing 350 hands.
I heart Crystal Math.

Eliot's page's numbers agree with yours.

He gives a SD of 6.0849, and 0.977466 as the probability of losing the bet. And doing 1 / 0.977466^350 gives 2913.
