El ejercicio dice:

Cuántas palabras se pueden formar permutando las palabras de BIBLIOTECARIA con la condición de que la T esté a la derecha de la C?

Mi pregunta es si hay otra forma de hacerlo que no sea por casos (supongo que la debe haber y debe ser accesible :roll: ).


Muchas gracias

Habia pensado el III, que dice algo asi:
III) con la condicion de que la T esté a la derecha de la C y la C a la derecha de la R.

como penso maca el segundo pero multiplicando por 1/3 suponiendo que en un tercio de los casos se cumple la condicion (al ser tres letras)
Sin embargo, esto me da el doble (86486400) de lo que deberia darme (43243200), osea que el resultado correcto seria multiplicar por 1/3 x 1/2, osea 1/6.
Alguien me puede explicar que estoy pensando mal y porque pasa esto ? Muchas Gracias :)

Lo que pasa es que aunque sean tres letras los casos son mas, fijate:
TCR TRC RCT RTC CTR CRT

De todas esas la unica que te sirve es RCT
Por eos tenes que multiplicar por 1/6
