The decades are quite close. For an average draw you will have:
1.1 numbers from Decade 0 (zeros)
1.2 numbers from Decade 1,2,3 (10's, 20's, 30's)
1.3 numbers from Decade 4 (40's)
The zeros (1-9) hit slightly less often because there are only 9 of them, compared to 10 in each of the other groups.
The most common result is to get 1 from each of the groups, followed by zero and two. 3 or 4 from a group is quite rare.
However, it is also rare to have a number from all decades (only 14%). The most common result is to have one decade missing (52%) followed by 2 decades missing (31%).
Good Luck!
