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