Za pomocą cyfr 1,2,3 używanych tylko jeden raz możemy utworzyć sześć liczb trzycyfrowych 123,132,213,231,312,321.

Ile liczb złożonych z trzech znaków I,V.X możemy utworzyć, jeśli użyjemy każdego znaku tylko jeden raz?

Odpowiedź:Otrzymamy sześć liczb.

Zaznacz tak jeśli podana odpowiedź jest prawdziwa lub nie jeśli jest fałszywa oraz wskaż poprawne uzasadnienie:

tak/nie ponieważ 1.postępujemy tak samo jak w rozwiązaniu opisanym dla licz 1,2,3/ 2. znak x musi być na pierwszym miejscu potem i,v lub v,i więc otrzymamy tylko dwie liczby
