What are the steps for calculating combinations and permutations.
How do I input the data such as a three digit set using 0-9.
You can enter combinations and permutations.
If the order of the selection matters (ie. 1st, 2nd, and 3rd place out of 40 contestants) use permutation. Enter:
40{shift}{nPr}3 and then [=] for your answer set (=59280 possible ways).
IF order doesn not matter (ie. a team of 3 from 40 possible members) then it is a combination. Do the same as above, but substitute {nCr} for {nPr}. (= 9880 possible ways).
For your question: a three-digit set, selecting from 0-9. There is no specified order, it is a combination. The total n=10 (there are 10 digits in the range 0-9) and you are selecting 3.
so.... 10[nCr]3 with give the number of possible combinations.
I do not think you can do that with your calculator.
Combinations and permutations reffer to mathematical definitons of such.
e.g How many five card combinations are possible out of 12 card set.
nPk=n!/(n-k)! and
nCr=n!/(r!(n-r)!)
