Question 1162805
.


In my life, I saw tens of thousands of Math problems, and solved thousands of them,


and I firmly believe that there is no Math problem longer than 5 lines of standard format.



All the rest is EITHER essays OR nonsense.



More concretely, it is not clear to me, for what purpose/purposes this post was submitted to the forum ?



If a person wants to learn on solving Probability problems, he (or she) should start from basic problems,

which all and always are short in their formulation.



Also, the laws of the nature are such that nobody will not only solve, but even read so long text

without a vital necessity, excepting it is of extraordinary interest, which is definitely not the case.



If a visitor does expect that the tutors will work instead of him (or her), then the visitor makes a HUGE mistake.

Our goal at this forum is not to work instead of students, making their job, but to TEACH them.



Assuming that the students are able to learn and really want to do it . . .
