Guide Wynnmath Guide (for All Your Calculations)

Okay so lets start the online homework quiz off strong with mythic odds:

Mythic drop odds = 7/1000000 x (1+(loot bonus/100))
Chance to get the item you are looking for = 1/(number of id-able items in that level group(including not the item type)
The longer a loot chest is standing unopened the more items will be in there. Deducing by this you should AFK near a chest with no life.
Chance on a max id'd item: 1/(Possiblerolls / Amountofhighrolls)
It is also possible to reroll items. Do what is logical. (chance x rerolls)
For example the chance i would get a max ws stratiformis from a mob with 130% lootbonus Will happen someday = 7/1000000 x (1+(130/100)
= 7/1000000 x (1+1.3)
= 7/1000000 x 2.3
= 16.1/1000000
= 1.61/100000
= 1.61x10^-5 x 100%
= 0.0000161 x 100%
= 0.00161% chance to get it to drop a mythic
0.00161% chance / 12 available items = 0.000134166667% to get a stratiformis
chance to get a max ws stratiformis = 0.000134166667% / (100Possiblerolls / 2Highrolls.
= 0.000134166667% / 50
= 0.0000026833333%
Also do it x4 for 3 rerolls which = 0.0000026833333% x 4
= 0.000010733333333%
chance to get it from a mob o_o i will be killing a lot of mobs


EDIT: because I thought it was logical to do 91-21. But I was wrong. I changed it to high roll. You need to get a 1.29x or 1.30x high roll from 0.30x to 1.30x. So it is actually 50 in the example. Props to Endertricity for discovering this
EDIT: also possible logical rerolls in the calcs. Props to 13threemc for this one.

I lost a bet...

Wat
I don't speak math

 

You look smart. I guess people tend to fly to you when they say "you may work in groups" in Math class.

 

1 / (0.00000191666667/100) is equal to 1 in 52,173,913 (rounded just cause)

This, while obviously being super impractically impossible, is actually pretty high chances compared to lotteries.

The chances of winning the Powerball Lottery is 1 in 292,201,338. Because of this,

You would get 5.6 max ws stratiformis before winning the Powerball Lottery

Of course, having one alone means that you can buy literally anything in the game, so why would you ever want 5 or 6 of them?

 

Overall, considering the drop chance of a mythic on average is 0.7 x 10^-6
These conditions are invalid if you use it in a calculations like chance of a "max identifications" or certain items when it dropped like "Stratiformis"

 

This is wrong
To get a 91% ws Stratiformis requires a high roll from 0.30x to 1.30x. More specifically, 1.29x and 1.30x round up to 91% only. This means that there is a 2/100 chance of getting max walk speed, or 1/50. Therefore you have to replace the 70 in one of your last steps with a 50.
So, the real final probability of getting a max walk speed stratiformis from killing a mob is 0.0000026833333%, or 1.4x as likely as you calculated.

Who's the bigger nerd now huh

 

Wow, didn't know about this. Thanks for bringing this up.

 

You both forgot to times it by 4 for the amount of logistically possible rerolls, amateurs.

 

Now make damage calculations.






Yeah seriously old calculation guide confuses me hard

 

Yorn guess what you are?







A NEEEEEEERD!!!!

 

I will see if I can use the old to make it, I will put a message saying I added it when it is done.
