What is (The diagram you drew)?
The answer to this problem:
You are given a 12 sided dice. The only way you can get a point is if you roll a number less than 5, but the number that you need decreases every time you don't get a number less than 5. If I roll a 3 on my first roll, what's the probability that I get a point?
