Hi...
This is a real problem in my work.
I have 8 fields
FIELD_A,
FIELD_B,
FIELD_C,
FIELD_D,
FIELD_E,
FIELD_F,
FIELD_G,
FIELD_H
I need to combine 4 of them; how many combinations should I have?
For example:
(FIELD_A AND FIELD_B AND FIELD_C AND FIELD_C) //combination 1
(FIELD_B AND FIELD_C AND FIELD_C AND FIELD_D)//combination 2
...
I've tried the combination without repetition formula but it doesn't work for me.
C = !n/r!(n-r)!
n = 8
r = 4
then C = 840
It doesn't make sense to me. What I'm doing wrong?
I appreciate any help.
Thanks
