Of the 125 Vtrac combinations, there are 35 that I call "boxed combinations". They are 111-112-113-114-115-122-123-124-125-133-134-135-144-145-155-222-223-224-225-233-234-235-244-245-255-333-334-335-344-345-355-444-445-455 and 555.
As you can see, there are 5 triples, 20 doubles and 10 with three unique numbers.
There are 10 that contain all odd digits, 12 that have two odd and one even digit, 9 that have one odd and two even digits, and 4 that contain all even digits.
The range of the sum of the numbers with the number of combinations:
9 = 5 8-10 = 13 7-11 = 21 6-12 = 27 5-13 = 31 4-14 = 33 3-15 = 35
The roots are more evenly distributed, either having 3, 4 or 5 combinations each.
Given any Vtrac number that has three unique digits, the probability that at least one number will repeat in the next drawing is 88.6%. If the number was a double, the probability is 71.4%. If the number was a triple, the probability is 42.9%. Overall, the probability is 72.2% [ 0.286*0.886] + [0.571*0.714] + [0.143*0.429].
