What's the EV ($$) of the following hand? Flush pays 5. Don't care about future multipliers or nothing like that.

I'm getting 18.319149 from WOO hand analyzer. Multiply that by $0.25 [how much you're betting on paytable], multipy by 9 [since you have 3 1x's and 2 3x's]. Getting $41.218?

If you're like me, you'll completely brick it! :-)~

Why not do it with the multipliers, it's more fun =)...

I'm going to assume you're playing 5 coins, so your flush pays "25" and your straight pays "20"... 9/5. From the hand you have you can make a pairs (A-Q-J), a regular straight, a flush, a royal flush, or you could brick =P. I'll do the math for them in that order... The total ER is the summation of each individual hands ER, since they are in fact separate draws from separate decks.

Hands Explained: 9/48 times you hit a high pair and win 25 cents (5*.5). 3/48 times you hit a straight and win $1 (20*.5). 8/48 times you hit a regular flush and win $1.25 (25*.5). 1 out of 48 times you'll hit a royal flush and win $200 (4000*.5). Lastly, 27/48 times you'll hit a brick and win 0, losing your total 25 cent wager on that hand.

Hand 1: (9/48)*(.25) + (3/48)*(1) + (8/48)*(1.25) + (1/48)*(200) + (27/48)*(-1) = .047 + .063 + 4.167 - .563 = 3.714, or a 371.4% ER.
Hand 2: [(9/48)*(.25) + (3/48)*(1) + (8/48)*(1.25) + (1/48)*(200) + (27/48)*(-1)] * 3 = [.047 + .063 + 4.167 - .563] * 3 = [3.714] * 3 = 11.142, or a 1,114.2% ER.
Hand 3: [(9/48)*(.25) + (3/48)*(1) + (8/48)*(1.25) + (1/48)*(200) + (27/48)*(-1)] * 3 = [.047 + .063 + 4.167 - .563] * 3 = [3.714] * 3 = 11.142, or a 1,114.2% ER.
Hand 4: (9/48)*(.25) + (3/48)*(1) + (8/48)*(1.25) + (1/48)*(200) + (27/48)*(-1) = .047 + .063 + 4.167 - .563 = 3.714, or a 371.4% ER.
Hand 5: (9/48)*(.25) + (3/48)*(1) + (8/48)*(1.25) + (1/48)*(200) + (27/48)*(-1) = .047 + .063 + 4.167 - .563 = 3.714, or a 371.4% ER.

Assuming your investment on each hand was 5 coins of 5 cents, then you have a total investment on each hand of 25 cents.

Hand 1 ER = .25 * 3.714 = .93
Hand 2 ER = .25 * 11.142 = 2.785
Hand 3 ER = .25 * 11.142 = 2.785
Hand 4 ER = .25 * 3.714 = .93
Hand 4 ER = .25 * 3.714 = .93

Thus, for your total investment of $1.25, your expected return was approximately $8.36... a 668.8% Expected Return. I think your "multiply by 9" is incorrect.

For the love of all that you hold dear show us the final picture! From you requesting the math... I fear the worse. Like someone getting outdrawn in poker going "What are the odds?!?!" =p

It depends on what card you threw away.


Dammit, I stand corrected by Mission. This should be information you know and can be accounted for. However my analysis should be very close.

I deleted my post after I noticed the card, your analysis is close to correct as the OP did not throw away a winning hand. The only thing is you must divide by 47 in all of your equations, not 48.

Dividing by 47 in all will increase the value a bit as paying hands become more likely, as a result.

Yep, already on it =).

Hand 1: (9/47)*(.25) + (3/47)*(1) + (8/47)*(1.25) + (1/47)*(200) + (27/47)*(-1) = .048 + .064 + 4.255 - .575 = 3.792, or a 379.2% ER.

Hand 2: [(9/47)*(.25) + (3/47)*(1) + (8/47)*(1.25) + (1/47)*(200) + (27/47)*(-1)]*3 = [.048 + .064 + 4.255 - .575]*3 = [3.792]*3 = 11.376, or a 1,137.6% ER.

Hand 3: [(9/47)*(.25) + (3/47)*(1) + (8/47)*(1.25) + (1/47)*(200) + (27/47)*(-1)]*3 = [.048 + .064 + 4.255 - .575]*3 = [3.792]*3 = 11.376, or a 1,137.6% ER.

Hand 4: (9/47)*(.25) + (3/47)*(1) + (8/47)*(1.25) + (1/47)*(200) + (27/47)*(-1) = .048 + .064 + 4.255 - .575 = 3.792, or a 379.2% ER.
Hand 5: (9/47)*(.25) + (3/47)*(1) + (8/47)*(1.25) + (1/47)*(200) + (27/47)*(-1) = .048 + .064 + 4.255 - .575 = 3.792, or a 379.2% ER.

Assuming your investment on each hand was 5 coins of 5 cents, then you have a total investment on each hand of 25 cents.

Hand 1 ER = .25 * 3.792 = .95
Hand 2 ER = .25 * 11.376 = 2.844
Hand 3 ER = .25 * 11.376 = 2.844
Hand 4 ER = .25 * 3.792 = .95
Hand 4 ER = .25 * 3.792 = .95

Thus, for your total investment of $1.25, your expected return was approximately $8.54... a 683.2% Expected Return.

To clarify things from the Wiz's hand calculator:

According to the hand analyzer... your ER throwing the 10 away is 18.319 units per hand... The math should be:

Hand 1: (18.319)*(.05) = .92
Hand 2: [(18.319)*(.05)]*3 = 2.75
Hand 3: [(18.319)*(.05)]*3 = 2.75
Hand 4: (18.319)*(.05) = .92
Hand 5: (18.319)*(.05) = .92

Given that your "unit" is a nickle... this would still give you an ER of $8.26 on your $1.25 total bet, about a 660.8% ER. Slightly off, but only just barely. I believe my above analysis is more exact. I'm showing a 19 unit expected return (per hand, before multipliers).

...NOW TELL US WHAT HAPPENED! lol

I'd bid it up to 50 just for the immediate opportunity factor and the thrill if all filled. Results please, we're waiting patiently and Romes worked his ass off.
