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