?

So there are four possible outcomes:

A B

So there are four possible outcomes:

If a rock allele from robot A combines with a sand allele from robot B, you get...

If you start with two Rockbots

Page 14: When people say “RANDOM” they often mean: LUCK Good luck, bad luck Improve your luck CHANCE What are the chances? You have a better chance UNPREDICTABLE.

and each has a sand allele,

Page 15: When people say “RANDOM” they often mean: LUCK Good luck, bad luck Improve your luck CHANCE What are the chances? You have a better chance UNPREDICTABLE.

and you got three Rockbots in a row

Page 16: When people say “RANDOM” they often mean: LUCK Good luck, bad luck Improve your luck CHANCE What are the chances? You have a better chance UNPREDICTABLE.

and you really need a Sandbot,

how many extra tries will it take?(0 means on the next try, no REDO)(means 4 Rockbots in a row, then a Sandbot)(means 27 Rockbots in a row, then a Sandbot)

Page 18: When people say “RANDOM” they often mean: LUCK Good luck, bad luck Improve your luck CHANCE What are the chances? You have a better chance UNPREDICTABLE.

How many extra tries will it take?

0 or 4 or 27 ?

If it is RANDOM there is no way to tell!
