Pe axa numerelor, in origine, se afla un purice. El sare aleator stanga -dreapta astfel: -pas 1 - 1mm -pas 2 - 2mm .... -pas 2017 - 2017 mm Dupa 2017 sarituri poate ajunge din nou in originea axei? Justificati raspunsul.


View the Solution Nu poate! Putem transpune problema in limbaj matematic, astfel: se pot aseza semnele + , - intre numerele 0-2017 astfel incat dupa efectuarea calculelor rezultatul sa fie 0? De la 1 la 2017 sunt 1009 numere impare. Oricum am aduna sau am scadea un numar impar de numere impare obtinem ca rezultat un numar impar. Prin urmare rezultatul nu poate fi 0.
