Solution
Vamos a resolver el problema paso a paso.
Primero, determinamos la probabilidad de que la película que Ali está viendo aún esté en reproducción cuando se sirva la comida.
- Tiempo de la película y tiempo de la comida:
- La comida se sirve 2 horas después del despegue.
- Ali empieza a ver la película justo al despegar.
Para que la película aún esté en reproducción cuando se sirva la comida, la duración de la película debe ser mayor a 2 horas. Sin embargo, no se nos da información sobre la duración de las películas, por lo que no podemos calcular esta probabilidad sin más datos.
Ahora, pasamos a la segunda parte del problema:
- Probabilidad de elegir al menos 2 películas de comedia:
- Hay 50 películas de acción, 10 de romance y 60 de comedia.
- Ali elige 3 películas diferentes al azar.
