Hello! I know how to find K Permutations for 1 group of numbers, but I need a formula to find the total combinations possible using the following criterea.
5 groups of Numbers (with varying amounts of numbers in each group).
Group 1 = 1,2,3,4,7,19,25
Group 2 = 5,7,15,29,35,40
Group 3 = 5,29,51,52,53,54
Group 4 = 19,22,23,24,25,32,27,28
Group 5 = 28,29,30,31,32,40,41
1 number from each group- using no duplicates in selections.
Need to find the total amount of 5 number combinations (such as 1 5 29 19 28).
Any help on a formula for this would be greatly appreciated.
