How count these combinations ?

[Jacko]

Me again, still counting combinations..
till now every given info here to me is working
and i learned a lot... but still not smart enough to find the next
result..

so..

-- Got list lotto combinations (A1 till F3000)
-- List of 6 nr each line
-- All numbers from (1 to 42)

Now ...how can i calculate how much times off the 3000 lines these kind
of combinations exists..

-- combination of 2 numbers
-- combi of 3 and 4 numbers

*i think it's maybe to complex to make such a kind of program*...
but maybe possible to calculate the combi of 2 numbers and
a (input cell) to check manualy for combi's of a 3th or 4th number
....out of the list


It would be kind of the one who knows a good solution to my problem
Greetings...

Hello Jacko,

If you are calculating combinations then the formula is nCk. Where n i
number of objects, 42 in your case, and k is the number of groups (
numbers at a time). To calculate the combinations the formula would be


(42*41*40*39*38*37)/(6*5*4*2*1) = 5,245,786

I don't think 3000 lines is enough space for your combinations.

Sincerely,
Leith Ros

I wouild read the requests something like this:
given a list of 3000 sets of six number lottery numbers, count the
combinations that contain each set of combinations of 2 numbers drawn from 1
to 42. I assume also for 3 and 4.

your formula can be done with the built in worksheet formula for
combinations

=combin(42,6)

In a previous post, Jacko received code that generates combinations.
