- Roll three origins and pick two of them.
- Place in desired primary and secondary slots.
Another option I considered was having them roll 3 sets (order enforced) and choose their favorite combo.
In my current game, everyone rolls randomly. If someone rolls an origin that some one else is already playing, they reroll that origin until they get something unique.
The basic deck will therefore contain 97 cards (2 of each origin plus one EH). The chance of being an Engineered Human has dropped to roughly 3%, but is still possible by either drawing the card or the same origin twice per the rules.
Engineered Human will always be secondary unless the card is drawn as the primary origin (first draw).
If I add more origins, I will probably add a second Engineered Human origin card to the deck. Drawing both would indicate the character is a Pure Strain Human (I'll have to figure out mechanics for one that I like, but I really miss that as an origin from the previous editions).
I plan on making a set of origin cards for players to draw from, then doubling the cards. There will be one Engineered Human card in there as well, as the expansions have greatly diluted the 5% chance of being an EH.

Ok, I have only the core set so I don't know how they modified the rolls to include the other origins, but your math is wrong. There is a 5% chance of any ONE number on any ONE d20. Engineered Human in the core set only required both d20's to have the same number. That is 5% x 5% for a total chance of 0.25%. Which fits the setting, as 'normal' looking humans are bloody rare.
However, I like the deck idea, and if you use the same amount of cards as origins (1 card per origin, however), replace and reshuffle after each draw, and only have the Enigneered Human come up if the same origin is drawn twice, it would have the same probability as rolling it.

Think of it this way: no matter what primary origin you roll, you have a 1 in 20 chance of getting engineered human for your second.
No, his math is right. Out of 400 possible combinations of two 20-sided dice, there are 20 results that give you engineered human. 5%.

Except these are independant events. The first die roll will NOT affect the second. Therefore they multiply.

The engineered human result uses the same math as snake-eyes (same number on both dice) except the chance of each number is 1/20.
1/20 (5%) x 1/20 (5%) = 0.25%.
Statistics is the only thing in advanced math that I'm good at. {Edit - When I'm awake.}

Exactly. NO MATTER WHAT YOU ROLL for your first origin, you have a 1 in 20 chance of getting engineered human. There are 400 possible combination of 20 origins. 20 of those combinations result in an engineered human.
Engineered human is NOT the same math as snake-eyes. Rolling a specific origin twice is the same math as snake-eyes. Rolling yeti twice is 0.25%. Getting engineered human is the same math as getting ANY set of doubles. Getting any origin twice is 5%.
Tell me, if you will, what the odds are of rolling doubles on 2d6? Now, how about 2d20? (Just to be clear, this is not advanced math. You'll have the right answer as soon as you take the next logical step.)
This has been a long week. Thank god it's 'spring break'.
I like the origin cards that anarchy made. Those are pretty awesome.
I've also allowed -- before Legion of Gold came out -- players to roll 1d20 and then choose whether they would take the D&D Gamma World origin or the Famine in Far-Go origin that corresponds to that roll. Then repeated a different roll for the secondary origin.
And sometimes I let players reroll if they've rolled something too close to what they played before, or what someone else is currently playing.
I don't really call people big chickens though.

Of course, not.
