SOLUTION: 1. The winning number of a lottery is a three-digit number between 000 and 999.

Your post contains 25 lines; 4 problems; each problem has from 4 to 5 questions.


It is MUCH MORE than any reasonable person may allow to himself (or herself), if he (or she) is in healthy mind.


There is THE RULE in this forum: 

        ONE and ONLY ONE problem/question per post

I repeat this message practically EVERY DAY; sometimes several times per day.


But still some visitors ignore it . . . 


I just tired of it.


This time I will make DIFFERENTLY: I will redirect your post to the TRASH SECTION.


I will do it in such a way that further use of this post will be impossible.


I think that this action will explain the rules of this forum to you even better than all my appeals.



      //  It is better to do (to make) something one time, than tell about it 1000 times . . .  //



So, please accept my condolences. 


And MEMORIZE please: those, who violate THIS RULE, work against their own interests.

        With it in mind, welcome to the forum !
