How many 5 digit combinations would it take out of 15 numbers(1-15)in order to have all possible combinations


I assume that repetition of numbers can't happen, and the order of numbers does not matter

So it is n! / (r! (n-r)!)
= 15! / (5! (15-5)!)
= 1307674368000 / (120 (3628800)
= 3003 combinations

5 number combination list


Too many to list (3,125). It would take you forever to get it unlocked. I would suggest bolt cutters and just spend the 20-30 bucks to buy a new one.

Where is the combination button


On any SHARP scientific calculator the combination button is always above the 5 (except the financial calculator). To get a combination type in the n value (the total number of items) press 2nd F and the 5 button and then type in the number of selected items and press =.

Does anybody know how many different combinations there are for the numbers 1, 2, 3, 4, 5 and 6?


That depends on how many of those six numbers you take.
If you only take one number, there are six combinations: {1}, {2}, {3}, {4}, {5}, and {6}.
If you take two numbers, there are fifteen combinations: {1,2}, {1,3}, {1,4}, {1,5}, {1,6}, {2,3}, {2,4}, {2,5}, {2,6}, {3,4}, {3,5}, {3,6}, {4,5}, {4,6}, and {5,6}.
If you take three numbers, there are twenty combinations.
If you take four numbers, there are fifteen combinations.
If you take five numbers, there are six combinations.
If you take all six numbers, there is only one combination: {1,2,3,4,5,6}.
In general, if you take 'm' objects out of a set of 'n' objects, the number of combinations is given by n!/[(m!)(n-m)!] where '!' is the factorial operator.

Number pad


You can't make the alternate characters like °, ®, ♂, σ etc with a combination number pad. You need to have a seperate number pad. I use a $20 plug in keyboard.
