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:
| | 0.05 | 0.2 | 0.1 | 0.05 | 0.6 | | 1 | 2 | 3 | 4 | 5 | | Number |
What is the probability of rolling a number that is bigger than 1 or smaller than 5? | |
