Fanontaniana matetika
Inona no fahasamihafana misy eo amin'ny fifampizarana sy ny fifampizarana?
Raha ny amin'ny fiovàna, dia zava-dehibe ny filaharana (miova ny vokany ny voalohany, faharoa, fahatelo); raha ny amin'ny fampifangaroana, tsy izany. Misy foana ny fiovàna mitovy amin'ny fampifangaroana.
Inona no atao hoe fiovana?
nPr = n! / (n − r)!. Ho an'ny zavatra 10 raisina 3 isan-kerinandro: 10 × 9 × 8 = 720.
Rahoviana no tokony hampiasako ny permutation?
Raha zava-dehibe ny filaharana: ny filaharana ireo tonga farany, ny famenoana ny toerana voalohany/faharoa/fahatelo, ny fametrahana olona mipetraka an-tsehatra, na ny fananganana fitsipika voalamina.
Inona no mitranga raha lehibe noho ny n ny r?
Tsy afaka mametraka ireo zavatra mihoatra noho izay efa anao ianao, ka tsy voafaritra ny vokatra ary manome tsipika ilay fitaovana.
Inona no nP0?
Ny 1 dia 1 — misy fomba iray ihany hametrahana ny tsy misy, ny fametrahana ny foana.
Inona no atao hoe nPn?
Ny isa 4 dia midika hoe 4, satria ny isa 4 dia midika hoe 4, ary ny isa 4 dia midika hoe 4.
