| SammyJankis Member since: Feb 8, 2010 Threads: 6 Posts: 16 | i read on the wizards site that insurance carries a 7.4% HA on a 6 deck shoe. How do you come to this conclusion? any help would be appreciated. i tried the math at a $1 bet. 96 wins(2 to 1, totalling $192) 215 loses -$23 23/311=0.07395 7.4% HA is this correct? |

You therefore have a 128/415 chance of winning 2x your bet and a 287/415 chance of losing 1x your bet. (128/415)*2 - 287/415 = -7.5% |

Yes, that's the correct calculation. (96/311)*2 - 215/311 = 7.4% |
