Tactics for the Swamp (Fortress).

Let me explain...
There's a formula, again from mathematics. :cool:

An 87.8% chance to take out 1 to 3 creatures. That is:
29.26% to kill 1 creature,
29.26% to kill 2 creatures,
29.26% to kill 3 creatures.
I hope I explained it clearly? :)

Hmm... Even the character from Bulgakov's unforgettable novel was aware of Newton's binomial... And the binomial distribution is taught in school. (It is assumed that each cow breathes independently). The expected value is 0.1N, the variance is 0.09N... With large N, it can be estimated using a Gaussian distribution.

For ten, the probabilities are approximately: [0.349 0.387 0.194 0.057 0.011 0.001 0. 0. 0. 0. 0. 0.] (to "breathe" 0, 1...; theoretically, it can be 10, but it is extremely unlikely)

Accordingly, no less than 1.2... [0.651 0.264 0.07 0.013 0.002 0. 0. 0. 0. 0. 0.]

You can check it in your Excel. (I can post a one-liner in Python)

THE MORE POWERFUL GORGONS YOU HAVE IN ONE STACK, THE HIGHER THEIR CHANCE OF KILLING THE MAXIMUM POSSIBLE NUMBER OF CREATURES!

The numbers are correct, and then something fantastic... The trials (breaths, in this case) are independent, so the probability distribution for a large stack is the same as for its components... That is, whether 10 attack, then 5, and then again 5.

And where does the magical one come from?)
