Just finished an animation segment for Art of the Problem which helps explain the concept of probability space and how it applies to dice. Great for anyone who hasn’t thought/heard of a probability space:

Thanks for your feedback. Are you a teacher? If so I’d love to hear how your class responds. Yes, I used “odds” in this case to attract attention of people interested in games.
You are correct though, I should label this Probability…

This is great! But not the way odds are commonly defined (in the USA, at least). I think you meant probabilities.

Odds are generally defined as

(number of favorable outcomes) : (number of unfavorable outcomes).

So, if the odds of something are a:b, the probability will be a/(a+b).

Still, I will probably be showing this in my stats class.
