<pre>Pasting these rules:
-A CLUSTER_EMUL -m set --match-set crop10_src src -m statistic --mode random
--probability 0.1 -j DROP
-A CLUSTER_EMUL -m set --match-set crop20_src src -m statistic --mode random
--probability 0.2 -j DROP
-A CLUSTER_EMUL -m set --match-set crop50_src src -m statistic --mode random
--probability 0.5 -j DROP
-A CLUSTER_EMUL -m set --match-set crop10_dst dst -m statistic --mode random
--probability 0.1 -j DROP
-A CLUSTER_EMUL -m set --match-set crop20_dst dst -m statistic --mode random
--probability 0.2 -j DROP
-A CLUSTER_EMUL -m set --match-set crop50_dst dst -m statistic --mode random
--probability 0.5 -j DROP
Getting these:
-A CLUSTER_EMUL -m set --match-set crop10_src src -m statistic --mode random
--probability 0.10000000009 -j DROP
-A CLUSTER_EMUL -m set --match-set crop20_src src -m statistic --mode random
--probability 0.20000000019 -j DROP
-A CLUSTER_EMUL -m set --match-set crop50_src src -m statistic --mode random
--probability 0.50000000000 -j DROP
-A CLUSTER_EMUL -m set --match-set crop10_dst dst -m statistic --mode random
--probability 0.10000000009 -j DROP
-A CLUSTER_EMUL -m set --match-set crop20_dst dst -m statistic --mode random
--probability 0.20000000019 -j DROP
-A CLUSTER_EMUL -m set --match-set crop50_dst dst -m statistic --mode random
--probability 0.50000000000 -j DROP
As you see here 0.1 suddenly becomes 0.10000000009.
