Sandradjer Posted March 24, 2023 Share Posted March 24, 2023 Imate 7 udzbenika (3 iz fizike i 4 iz matematike, medjusobno razliciti). Na koliko nacina se mogu poredjati na policu ali tako da dva iz fizike nisu jedan pored drugog? Uzrast 15 godina Quote Link to comment

Ras Posted March 24, 2023 Share Posted March 24, 2023 (edited) Edit: 120 Između 3 udžbenika fizike mogu se poređati 4 udžbenika matematike na 10 različitih načina: (2,1,1,0), (0,2,1,1), (0,1,2,1).... Kako se radi o različitim udžbenicima za svaki od predmeta, udžbenici iz fizike mogu međusobno menjati mesta, jednako kao i udžbenici matemtike: 3*4*10=120 Edited March 24, 2023 by Ras Quote Link to comment
