Can I have some help with Math? Hypothetical scenario about status-chance.

[TwiceDead]

So, from the wiki the calculation for status-chance is  Status Chance = 1 − (1 − Chance per Pellet)^{Number of Pellets} , right?

But here's my hypothetical scenario... What if you had a different status-chance for each pellet?The original forum assumes the status-chance for every pellet is the same.

So, say you fire 4 pellets, each one has a different status-chance... 

Status-Chance per-pellet: 
Pellet 1 : 10%
Pellet 2 : 15%
Pellet 3 : 20%
Pellet 4 : 25%

How would would the formula look now? Do you just use the average number instead? (0.10+0.15+0.20+0.25) / 4 = 0.175?

So..
1 - (1 - 0.175)^4 =
1 - 0.825^4 = 
1 - 0.4632 = 0.5368?
0.5368 x 100 = 53.58? 

I am asking because I don't know for sure, and I would like to... Planning to take up math after new-years, as I am horrible at it. Still fun to try though. 

EDIT: Redid some stuff to clarify, since I used the wrong numbers to begin with... D'oh.

the formula from wikia is :

Status Chance = 1 − (1 − Chance per Pellet)^{Number of Pellets}

so lets say your stats is 10%

and number of pellets shot is 10

status chance

= 1 - ( 1 - 0.1)^ 10

= 1 - (0.9) ^ 10

= 1 - 0.3487

= 0.6513

= 65.13%

 

Maths lesson :

1. In probability

1 = 100%

0.1 = 10%

2. Always do what is inside the bracket 1st

3. Always do things that have bracket

4. Then only do things wihout bracket

all pallet has the same status chance as your mod.

check the status at your gun when mod.

That's all certainly helpful advice, but it doesn't really answer my question... But I do appreciate the guidance nonetheless, thank you.
