Bazooka case: or how parts are not random
lucifer_ultionis
In this article I will prove, using basic math that the admins are lying toyou.
Here's how:
In the info box of the collections it is written: You can find the collection parts in the Battle page. Fight and you will receive RANDOMLY some of them!
Is it really RANDOM? 🙂
You probably think it's not! But can you prove it?
Here's my situation. I've receive😛
Stocks: 3
Barrel: 6
Scope: 3
M6A3 rocket: 0 !!!
Triger kit: 6
Random is when all the possibilities have EQUAL Probabilities of appearing. That is a Stock is as likely to appear as a Barrel and as likely as an M6A3 rocket. The logic is the same as that of tossing a dice (the faces of a dice have equal probabilities of showing up)
So, you might wonder, WHAT would be the Probability of my outcome (we can consider yours if you want in the comments) IF we ASSUME the items were indeed appearing RANDOMLY as admins have said (and made us spend lots of our savings, as in my case)
Since there are 5 items, it must be the case that each one of them has a 0.2 probability of appearing (otherwise it's not random)
One can ask: What is the probability of NOT getting a Rocket if N items are received? (N = m1+m2+m3+m4+m5, where m1, m2, ... = number of items of the 1st type, 2nd type and so on)
Probability(of NOT receiving ANY rocket) = (1-0.2)^N
therefore in my case:
The Probability(of NOT receiving ANY rocket) = (1-0.2)^N = 0.8^18 = 0.0180144
In Percentage terms = 1.8% With a 95% confidence interval we can conclude that the distribution of the ITEMS IS NOT RAndom! And admins HAD you! 🙂
Literally! Do you feel ashamed for being stupid and spending your savings? You shouldn't BUT ADMINS SHOULD! Cause it's not nice to lie to the people that bring you revenue and play your game!
Method 2: (a lil bit more advanced)
You can also use a multinomial to calculate what is the probability of getting the EXACT outcome you have, assuming that they appear randomly.
Probability of getting your outcome 😞
N!/(m1!+m2!+m3!+m4!+m5!)* 0.2^m1 * 0.2^m2 * 0.2^m3 * 0.2^m4 * 0.2^m5
Where m1, m2, ... = number of items of the 1st type, 2nd type and so on
N = m1+m2+m3+m4+m5 (total number of items you got)
Then if will involve calculating the cumulative distribution of getting up to m1, m2, m3...

eu nu am stock.. vreau stock!!!
I guess we should try to find out if somebody managed to assemble a bazooka first.
true... it's randomly randomized
I just got a msg from admins 😃
Who REPORTED IT??? MAY I know??? 🙂
4/5 pieces (9 total), no rocket yet

Everybody is aware rocket part is pain in a**. I have similar situation like you.
I understand they didn't want all people collect 20 bazookas in few days and steal battle hero medals from players with high strength.
But they could make it really random and all parts have same probability as rocket now. But I guess people wouldn't be that much motivated to fight like now but anyway we will end up with hundreds of worthless parts.
However I like this change, it could bring some balance to game since new players could never catch up with old. And this change gives them option not to reset strength.
Ah... Thank you! I was starting to think it was just me. I'm in a similar situation to...
Math is math and RANDOM is not random, mostly when it's about rocket... science.

Someone got one i think. I was against a bazooka but didn't fight since my internet went down. But other than that, I have seen no one.
at least it brought a little excitement into this game😁))))
I managed to find an entire bazooka. Using it gave me another one. And that was all🙂
In this moment I have:
Stock - 6 pcs
Barrel - 2 pcs
Scope - 0 pcs🙁
M6A3 Rocket - 1 pcs
Trigger Kit - 4 pcs
They are random, but not equally so. Stocks and Triggers, you can find a lot. Scopes and Rockets very, very hard...
I have tons of scopes... no rockets...
Read the statement carefully. It doesn't state that you will get a random piece, it states that you will randomly GET a piece.
I got a complete one fairly easily.
within 3hrs got me 2 bazookas 🙂, talk about math science...
I get 3 bazookas yesterday, so I guess 1,8% chance is a little low calculation. 😉
I was missing a scope but they gave it to me as a prize for completing the mission. Have you clicked the button yet?
you don't understand the meaning of random. random only means that you can't predict the outcome. 99%/1% probability is still random.
Thank you all for your comments 🙂
I did receive a msg from the admins though with a confirmation and an explanation for why things are the way they are. I'll post it in an update.
I got a few parts of each type except rocket. A friend got the rocket as the first part that ever dropped...
Random means any piece may drop, so even if you have 100 of 1 and none of the other four, it is still random.
it is NOT random to start getting only the one you are missing.
I have a rocket in my pocket.
Err, random does not mean "equal chance of any outcome".
Rolling 2 dice is a random generator, but you will end up with a lot more 7s than 12s.
I got the rocket first so i'm guessing it is random.
Random does not mean you're guaranteed a predictable spread in the outcome. Ever played roulette? It's a great example of how random random can be. I've seen the same number turn up three times in a row, yet the odds of that occurring are 1 in 50,653. I don't even play that often.
Anyway, as Rigour6 suggested, grab yourself some dice and see for yourself the results you get from random number generation.
your math is fail as you dont know what is the % to get any item
Got lot of rockets,cant get barrel
i have rockets but not a stock.
the beauty of probability is that it only says how things are most likely to be not how they will be, you can flip a coin 100 times and always get heads, its not very probable but it is possible.
similarly due to the space between atoms it is possible that over the lifetime of the universe if you run into a wall over and over again eventually all of the empty spaces will line up with the full spaces and you'll pass through the wall. not likely, but possible.
Rigour : "Err, random does not mean "equal chance of any outcome".
Rolling 2 dice is a random generator, but you will end up with a lot more 7s than 12s."
@Rigour .. the faces of the dice have equal chances of appearing. Therefore the AVERAGE value of rolling a dice E[X]= 3.5
If we denote X1= the random value of the first dice, X2 = the random value of the second dice
The expected value of rolling two dices is:
E[X1+X2] 3.5+3.5=7
That's why, when you roll 2 dices, you're more likely to get the sum of 7 than ANYTHING else.
That said, the SUM of of the values IS a RANDOM VARIABLE, but definitely DOES NOT follow a UNIFORM distribution.
However, choosing something "RANDOMLY" is exactly what I mean.
Vive les matheux!
You're damn right!
I thought I was the only one..
7 Stocks, 6 Barrels, 3 Scopes, ZERO rockets and 6 trigger kits.
Coincidence? I don't think so!
Well, in computer programming you can't have a pure random function, can you? But using some simple tricks, you can get pretty close. Still, this is too far from close. My guess would be that the admins have programmed the game in a way that the items have different possibilities of appearing. And rocket must have the lowest possibility! That would also explain why some people - very few though - encountered some rockets.
To everyone who's trying to be a smartass proving this article wrong, let me tell you something about random, your dog getting hit by a car is random, someone robbing you out in the street is random, dying at your birthday is random. But ALL of these facts happening simultaneously is certainly not random! I mean I am 30 years old and I could die in my sleep tomorrow night, but the odds of that would be 0.000001%. How would you define "possible"? What would be the odds of possible? 10%? 25%? 40-50%? But in my book 0.1% is NOT possible, at least it's a very long shot! You might as well be abducted by aliens tomorrow evening!

Not easy here too... No logic involved on these itens distribution.
Stock - 31 pcs
Barrel - 42 pcs
Scope - 0 pcs
M6A3 Rocket - 6 pcs
Trigger Kit - 30 pcs
Yep, that's me!
