Des de matem\u00e0tiques, amb l\u2019alumnat de 1r d\u2019ESO estem treballant l\u2019atzar.<\/strong>
Hem estat fent experiments senzills com llan\u00e7ar daus, taps o xinxetes per observar qu\u00e8 passa i recollir dades dels resultats. A partir d\u2019aquestes activitats, hem descobert que, tot i que no podem saber amb certesa quin resultat obtindrem en un sol llan\u00e7ament, s\u00ed que podem preveure la probabilitat<\/strong> que passi un determinat esdeveniment si repetim l\u2019experiment moltes vegades.<\/p>\n

Aix\u00ed, hem apr\u00e8s que la probabilitat<\/strong> \u00e9s una manera de mesurar el grau de certesa<\/strong> que succeeixi un esdeveniment<\/strong>, i que es pot expressar amb fraccions, en tant per u (nombres entre 0 i 1) i en tant per cent. Tamb\u00e9 hem vist que, com m\u00e9s repeticions fem, m\u00e9s s\u2019acosten els resultats a les probabilitats te\u00f2riques, per aix\u00f2 hem llan\u00e7at m\u00e9s de 1000 vegades una moneda.<\/p>\n

Tamb\u00e9 hem vist que al llan\u00e7ar dos daus i sumar els seus valors podem obtenir diferents resultats, per\u00f2 no tots ells s\u00f3n igual de probables. Aix\u00ed, a partir d’ara els entenem millor perqu\u00e8 el doble sis \u00e9s menys probable que esdeveniments que obtenir un resultat que sumi set.<\/p>\n
