Ive read so many horrible ways people judge theyre odds in this game lately so i will make a short guide to it so people hopefully can understand how it works.
First let us do a quick example.
If you throw a dice (1d6) you will get a number from 1-6, each of those have the odds 1/6 to appear or 16.67% chance.
Now what is the odds of getting a 1 in 2 throws in a row (
Rolling 2d1:
(1, 1) )?
I have the feeling a lot in here would say 16.67%, this is ofcourse wrong.
Reason is that first you throw one time, odds for it hitting a 1 is then 16.67%, but if you want it in the second throw aswell you have to make the assumption you also got it in the first. The way to calculate the odds for two throws in a row hitting a 1 would then be to multiply the odds from throw one, and throw two: 16.67% x 16.67% = (1/6) X (1/6) = 1/36 = 2.77%
Now over to AA50 odds:
A bit general odds:
Calculating odds of a battle with more units is highly complex as killed units are removed in every round someone score a hit. This makes it almost impossible to make a code that gives the exact odds for an attack. To counter this battlecalc constructors have used simulations of the actual combat you type in and give you an estimate for the odds. As you can see if you try the same battle in tripleA more times you will see a different result every time if the battle is semi complex like Karelia turn 1 attack of 3inf 1art 3fgt vs 5inf 1art. Also these battlecalcs only show the odds of winning the battle with 1 attacking unit surviving, it also says whats the most likely result of attacking units surviving but this is NOT what the odds are refering too. The odds stated refers to one unit surviving. The odds of more units surving will allways be lower then the odds of 1 unit survivng.
To calc the odds for 1 unit survivng the program runs the battle maybe 100 times. Then it adds up all the battles with 1, 2, 3…etc units survivng and dividing it by 100. And you then get an estimate for the odds that youre attack will survive.
Now over to more battles succeeding at once:
Sometimes in AA50 you are in the need off more then one attack succeeding at the same time, like if you hit the eastern front with Germany you want to take 3 territories for the bonus. So what you are interested in is the odds for ALL three attacks suceeding at the same time.
To calculate this you first need to determin the odds for each of the attacks individually, then as in the dice example over you need to multiply the odds for each off the three attacks to determin the attacks combined will succeed.
Now look on a German opening Turn 1.
Assault on Leningrad
- Take Karelia ( 3 infantry, 1 artillery, 3 fighters , cruiser/transport
Eastern front assault:
- Take and Hold Baltic States ( 2 inf, 3 tanks )
- Take and Hold East Poland ( 1tank, 2 inf, 1 art )
- Take Ukraine ( 3inf, 1 art)
Navy assault
- Sink UK battleship + transport ( 2 sub, 1 fighter )
Egypt assault
- Attack Egypt with 1bmb, 2inf 1art 2arm
Odds for the attacks individual is then:
Assault on Leningrad 79.2% for wininng with at least 1unit surviving.
Assault on Baltic States 96.3% for at least 1 surving land unit a bit lower if you want odds for more to survive.
Assault on Eastern Poland 98.1% for at least 1 surving land unit a bit lower if you want odds for more to survive.
Assault on UKraine 94.4% for at least 1 surving land unit a bit lower if you want odds for more to survive.
Assault z2 84% for at least 1 surviving unit, dont care about the subs here so doesnt matter much
Assault on Egypt 75.3% for at least 1 surving land unit a bit lower if you want odds for more to survive.
Combined odds
Now to the interesting part, each of these attacks have no lower then 79.2%. Lets see what happens if we set as a demand that all 6 attacks have to suceed for us to have a successfull turn.
Odds for all these 6 attacks will succeed in same game turn 1: 0.772 x 0.963 x 0.981 x 0.944 x 0.84 x 0.753 = 0.435 = 43.5%
As we can see we will only have a chance off 43.5% of these 6 attacks to succeed at the same time. If you are looking for a solid gameplan you would like to get the combined odds of MUST accomplish goals maybe up to 90-95%. Though in some situations where the risk / reward ratio is great you might be willing to do an 20% individual odds attack, just becouse it wont hurt you much if you fail, but benefit you great if you succeed. In those cases you should NOT add that single attack into the multiplum you check to find if the must succeed attacks have high enough odds of succeeding for you to be willing to do it.

Plz give me feedback on this guide, i would like to improve it so people wont start more threads based upon flawed statistics as im a geek who gets provoked by people using maths the wrong way to deffend theyre tactics or opinions. I might also add a paragraph about why this makes low luck a whole different game then dices in AA50 in the future, but that will have to wait.
Also english is not my native language so spelling errors do occur, and i would love if someone would help me correct it :)
