¿Qué son las probabilidades?

Imagínate que pudieras predecir qué tan probable es que algo pase - eso es exactamente lo que hacen las probabilidades. Son una medida que te dice qué tan posible es que ocurra un evento específico.

La probabilidad simple se calcula con una fórmula súper fácil: divides el número de resultados que te interesan entre el total de resultados posibles. Por ejemplo, si lanzas una moneda, hay 50% de probabilidad de que salga cara porque hay 1 resultado favorable (cara) entre 2 posibles (cara o sello).

Puedes expresar las probabilidades como fracciones, decimales o porcentajes. Cuando lanzas un dado y quieres sacar un número impar, tienes 3 números impares (1, 3, 5) de 6 posibles, lo que te da una probabilidad de 3/6 = 0.5 = 50%.

¡Dato curioso! Las probabilidades siempre van de 0 (imposible) a 1 (completamente seguro). Un 50% significa que tienes las mismas posibilidades de que pase o no pase.

The app is very easy to use and well designed. I have found everything I was looking for so far and have been able to learn a lot from the presentations! I will definitely use the app for a class assignment! And of course it also helps a lot as an inspiration.

This app is really great. There are so many study notes and help [...]. My problem subject is French, for example, and the app has so many options for help. Thanks to this app, I have improved my French. I would recommend it to anyone.

Wow, I am really amazed. I just tried the app because I've seen it advertised many times and was absolutely stunned. This app is THE HELP you want for school and above all, it offers so many things, such as workouts and fact sheets, which have been VERY helpful to me personally.
