An introduction to expectations and theoretical hold

dude has a mensa mind

For real...

In fact, I think Mensa's "too dumb" for him; I'm actually "mensa qualified" based on my scores on standardized tests, and there's no way I'd be remotely comparable to Ganchrow.

No I understood the different purpose of each equation, I was just wondering where the second one comes from.

I think if you take the first equation, divide that whole thing by the units wagered, you should get the percentage. I just can't find any way to rearrange the first equation into the second.

He just divided both sides of the equation by "amount lost." More appropriately, it should say "amount risked," but same thing.

1) E(unit profit) = (win %)*(amt won) - (loss %)*(amt lost)

2) E(% won) = E(unit profit)/amount risked = E(unit profit)/amount lost

3) E(% won) = E(unit profit)/amount lost = win(%)*(amt won)/(amt lost) - (loss %)*(amt lost)/(amt lost)

4) E(% won) = (win %)*(amt won)/(amt lost) - (loss %).

In a parallel universe could you have different results due to probability?

Yes, prob no mean cosmic ramifacatioms, it only talk that game. The repeat it coins. Parallel un vers it not money[math] that only in bronks
