[2] | A Crazy Die has 5 sides, but each side has a different probability of being rolled. This is is the probability distribution of the sides being rolled:
| | 0.15 | 0.15 | | 0.15 | 0.55 | | 1 | 2 | 3 | 4 | 5 | | Number |
What is the probability of rolling a number that is bigger than 2 and smaller than 1? | |
