Is there a way to create a formula, to calculate the odds for a combination of the following possibilities; without running all the different possibilities, through each lottery combination? It's easy to figure out the odds for each possibility, per filter; but to figure out the odds, for a combination of the filters, is driving me crazy. To run all the possibilites through each lottery combination, would be very time consuming; and I'de doubt that you could have a text file that big. A formula, if possible, would be the only solution. If you can help, or point me in the right direction; email me at cjames14@qwest.net. I'd REALLY appreciate it!

Filters:

Excluded #'s: (1-49) 49 possibilities

Sums: (21-279): 259 possibilities

Even #'s: (0-6): 7 possibilities

Low #'s: (0-6): 7 possibilities

Consecutive #'s: (1-6): 6 possibilities

Lowest # Drawn: (1-44): 44 possibilities

Highest # Drawn: (4-49): 44 possibilities

What makes it hard to calculate the odds; is that changing one filter affects the other filters. It's hard to figure out, how many combinations are left in the remaining filters; and then to filter from the remaining.

• I received several more questions on the topic of number of lotto combinations when grouping the numbers by *low/high* and *odd/even* criteria. Most of the questions seemed to be legitimate. I worked out relevant formulae regarding the lotto odds for grouping the numbers by *low/high* and *odd/even*. Read this page:

* Software and formulae to calculate lotto odds* using the hypergeometric distribution probability.

Also, I released software applicable to the pick-3 lottery game. The lottery software can generate combinations that apply the low/high and odd/even digit grouping. Read this page:
