i cannot return a warning, but i did message her to tell her everything was fine ...

I reported her, because i didn't knew she was kidding or she got crazy that moment

if i had suspended her (which the conduct didnt warrant) i could have reinstated the account; but as is, a warning is just a way to for us to try to nudge a person into conforming.

Answer 16

Miss @mary.rojas Can I get a help from you ?

Answer 17

Ok, lets see here...
Do you have any idea what to do or have any examples/notes?

Answer 18

Miss Mary I am weak at 'Combinatorics'. I am not understanding it.

Answer 19

What would you think you would have to do, anything?

Answer 20

I am totally Blank in this chapter

Answer 21

ok I dont know how to do advance one (I use to but it has been awhile since I have done these) this but I will try my best to help :)
Ok well first thing/rule: when it says "2,3,4,0,8,9, no digits repeated", that means you do this: 5 digits* 4digits (Must subtract a digit from the total 5 because you can not repeat that one)*3digits(Must subtract two digits from the total 5 digits because you can not REPEAT those same 2 digits)* 2(Must subtract 3 digits because you can not REPEAT those same 3 digits)*1(Must subtract 4 digits because you can not REPEAT those same 4 digits again)........
That is what you do when you "CANT REPEAT", each time you are multiplying the total but eliminating a digit/option so it is not REPEATED.
Oh my.. does that make sense?

Answer 22

So it is 5*4*3*2*1 just for the "No repeating" part. That is not the answer, just a part of it.

Answer 23

Yes It helped me... I fused your answer with @deena's answer.... and do you know what happened... I get to the conclusion, that your answer really made a sense

:)

Thank you @mary.rojas . I got 100 as the answer.

Answer 24

Answer 27

Oh no, tell me if I ever am and I will try to say it better/less confusing.
Or even find someone to explain it better. I will NOT get mad :).

Answer 28

No No... it really helped me ... Trust me... can we carry on to next question ?

Answer 29

yes, post it on a new post because this one is long
