- The table shows data on the occurrences of prime numbers on draws, considering all draws of powerball (with the current matrix).
- Actual occurrences are the real total occurrences of a determined quantity of prime numbers on draws.
- Expected occurrences are the expected occurrences of a determined quantity of prime numbers on draws, according to mathematical probability.
- Last draw is the most recent draw in which occurred a determined quantity of prime numbers.
- Shortest interval is the shortest gap between draws in which occurred a determined quantity of prime numbers.
- Longest interval is the longest gap between draws in which occurred a determined quantity of prime numbers.
- Current interval is the current interval since the last draw in which occurred a determined quantity of prime numbers.
- Average interval is the general average of intervals between draws in which occurred a determined quantity of prime numbers (until the last draw in which occurred a determined quantity of prime numbers).
- The actual and expected occurrences tend to get closer to each other the largest the sample.
