Question from Joe, a student: Hi Everyone, I'm trying to find out how many combinations are possible out of 1-8 using only 4 numbers, but with no repetition of a single number in the 4 number sequence. EX: 2,3,2,5 wont work. Is it possible to create a list, and if so did my calculator lie to me when i got 70 as an answer? Thanks For Your Time |
Hi Joe,
Look at the note that Stephen sent to Rene in response to a similar question. Do you get 70 combinations using his method?
