Well... That's your hint.

also all this looks a bit hocus-pocus to me. a bit far fetched..

I'm not doing the problem for you. Have you learned about combinations/permutations?

So what I'm asking is - tell me what is tripping you up. What exactly do you know. What is causing issue? If you don't want to put in the work and just keep demanding that I 'give you the number' then I'm not doing anything. Best of luck. I want to help but you have to recognize you aren't the one with any power here.

Maybe there are multiple algorithms, that can be applied to get the same result.. i d k.

Whats tripping me, is that I suspect this science is random and the algos are not deterministic by nature.. but more like acupuncture.

Let me put it to your language - the probability of your answer being different than my lecturer is higher than 50%

Am I right?

these probabilities just have to be added. no need for combinations, permutations or derivations

but what is the probability of exactly 12 votes?

is it

ok.. clearly there are 4 cases, that qualify: 12, 13, 14 or 15 votes.

but what is the probability of exactly 12 votes?

is it**0,7^12 * 0,3^3** (inclusive of denials) or just **0,7^12** (non-inclusive of denials) ?

but what is the probability of exactly 12 votes?

is it

neither. Once again think about the hint I gave you. Because if you have exactly 12 votes - how many ways are there for that to happen? Think about the definition of combinations (I even narrowed it down for you - you're welcome).

my friend, by saying "neither" you have already proven, that your number is different, than the one my lecturer sent me.

so you are wrong and i am right - it is non-deterministic hocus-pocus.

if i understand correctly you want me to solve this problem with binomial distribution, but it is unnecessary, cause why would i trust your algorithm more that an authoritative university professor? mmh? makes no sense right.
