Can someone explain why at 10x, the HE isn't a perfect 1/10 of the HE at 100x? Why is the HE at 10x not .14%?

Even factoring in the push, shouldn't the HE just be 1/10th?

Also, on the pass line plus odds, at 10x, the HE is a combined .184%, whereas the combined HE on 100x is .021%. Why isn't the HE at 10x just 1/10 of 100x? Meaning, why isn't the HE at 10x .21%?

Thanks

Idk if this helps, but here's an excerpt from an Ask the Wizard from the craps index:

Quote:Is the combined house edge in craps of 0.014% (taken from your chart) on don’t pass and laying 100x odds the lowest house edge of any casino game? And, does 0.014% casino edge mean that for every $100 you wager you will lose 1.4 cents?

There are still video poker games that with proper strategy pay over 100%. I’ve also seen a blackjack game at the Fiesta Rancho and Slots-a-Fun in Las Vegas that had a basic strategy advantage. As I argue in my sports betting section betting NFL underdogs at home against the point spread also has resulted in a historical advantage. So 100x odds in craps is still one of the best bets out there, but not the very best. Yes, 0.014% means that per $100 bet you lose 1.4 cents on average.

we are dealing with a ratio (a/b)

for the don't

10x = 3/2420

100x = 3/22220

the denominators

22220/2420= 101/11 = 9.1818...

expected value (EV) = house edge (HE) * average bet resolved (Bet)

from that we can get

house edge (HE) = expected value (EV) / average bet resolved (Bet)

or just using multiply

3/220 * (1/(1+M)) where M = odds factor

don't (counting ties)

M=10;

a= 3/220 * (1/(1+M));

a

M=10;

a= 3./220 * (1/(1+M));

a

M=100;

a= 3/220 * (1/(1+M));

a

M=100;

a= 3./220 * (1/(1+M));

a

(16:31) gp > M=10;

(16:31) gp > a= 3/220 * (1/(1+M));

(16:31) gp > a

%3 = 3/2420

(16:31) gp > M=10;

(16:31) gp > a= 3./220 * (1/(1+M));

(16:31) gp > a

%6 = 0.0012396694214876033057851239669421487603

(16:31) gp >

(16:31) gp > M=100;

(16:31) gp > a= 3/220 * (1/(1+M));

(16:31) gp > a

%9 = 3/22220

(16:31) gp > M=100;

(16:31) gp > a

%12 = 0.00013501350135013501350135013501350135014

the function of a fraction gets to most people

not intuitive always

Quote:klimate10On the WoO website, the combined house edge on 10x for the Don't Come and 100x is .124%, whereas the combined HE on 100x for the DC is .014%.

Because with 10x, your total bet is 11 times the DC bet, while with 100x, your total bet is 101 times the DC bet - but in both cases, the house edge in terms of dollar value is the same.

same simple reason that the average bet ratio is not 10 to 1Quote:klimate10Also, on the pass line plus odds, at 10x, the HE is a combined .184%, whereas the combined HE on 100x is .021%. Why isn't the HE at 10x just 1/10 of 100x? Meaning, why isn't the HE at 10x .21%?

avg bet = 1+(2/3)*M

M = odds factor

the ev per unit bet = 7/495

a = avg bet for 10x = 7 2/3

b= avg bet for 100x = 67 2/3

b/a= close to 8.826086957

(18:00) gp > a = 23/3;

(18:00) gp > b= 203/3;

(18:00) gp > b/a

%3 = 203/23

BBB,

This is the link. https://wizardofodds.com/games/craps/basics/

But the kind gentlemen above have answered the question. It's not a 1/10th ratio. Makes sense.

I’m not sure you understand the meaning of “simple”
