# Calling all Math Wizards

Quick query for anyone with a better head for math than me (which is practically everyone, including my 11 year old kid).

Just launched a Raid. Bastet was the enemy tank.

As usual Bastet fired first… 45% chance for allies to dodge special skills.

My team were in very poor shape so i launched everything that was charged… Matilda, Alucard and Goseck. Total of 13 potential hits from those three specials.

12 were dodged.

Basically, Bastet got a fiend from Matilda and everyone else dodged everything I threw at them.

Anyone know how to work out the odds for that?

Not sure but it’s ‘maths’ not ‘math’, only Americans say it incorrectly.

Hope it helps

The probability of that particular outcome (exactly 1 hit lands and 12 misses) is 0.049%.

The hits follow a binomial distribution with the following probability mass function:

Hence the probability of landing exactly 1 hit (k = 1) out of 13 hits (n = 13) with the probability of success being 1-0.45 = 0.55 equals:

f(1,13,0.55) = Pr(X = 1) = (13,1) * 0.55^1 * (1-0.55)^(13-1) = 13!/(1! * (13-1)!) * 0.55^1 * (1-0.55)^(12) = 0.00049 = 0.049%.

The probability of landing 1 sucessful hit or none is 0.052%.

Hi,

It’s easy: (12*100) / 13 = 92.30%

45% skill , 92.30% reality

Come on now. Americans speak American, not English. That’s why it’s “Math” and not “Maths” here. Alright!

Sure, because in England you study histories, psychologies, and economicses as well.

Thats right IF the evenrs are really independent. I often observe similiar behaviour, no dodge at oll or dodge everything. With revive or resurrection its the same, often no fighter revived, in the next battle one of them revived five times in a row.
If they cache some flags or seedings for rng, we would have some couplings of events, we can no longer treat them as independent. This is in better accordance with the observations of many players.
Ungortunately without knowing the used algorithms, which Parameters were cached and how long, no prediction can be made.

Happy gaming

Maths??! We don’t do that here

Dodge works as follows:

• 99.99% on defense
• 0.01% on offense

Spot on Maths-Teacher not Teachers lol! Still some way to go and nothing personal

I don’t know how we ended up here!!! This is all your fault @Ghost

Lol me again, I have that negative effect I think.

But two negatives make a positive, right?

He’s brilliant @Luna, ages since I’ve seen that

That’s probably the funniest Michael Macintyre ever was.

I love my visits to Murica but it’s a strange place devoid of the letter U

Interesting… How it would be with our bot?
1-45 = dodge
46-100 = hit

@discobot roll 13d100

Edit: 7 dodges, 6 hits
