You would use combination when order does not matter.

Is how many ways can you choose 4 Cd's from a stack of 8Cd's a combination or permutation?
Any 4 from 8 is a permutation, solved by the use of factorials: 8!/((8-4)! x 4!) which simplifies to (8 x 7 x 6 x 5)/(4 x 3 x 2) ie 70 different ways.
How do you solve math permutations?
A permutation is the rearrangement of objects or symbols into distinguishable sequences.You can use the formulas. nPr=n! / (n-r)!where n the set from which elements are permuted and r is the size of each permutation (! is the factorial operator)For example: How many ways can you rearrange the word math? 4P4=4!/(4-4)! 4P4=4!/1 4P4=24
How many 6-digit numbers can be formed using the digits 23456 and 8 with repition?
Order does matter in this case so you need to use the formula for a Permutation with repetition allowed. This would be n^r where n=6 different numbers and r=6 possible places for each number to go when forming the full 6-digit number. 6^6 = 46,656 possible digits
Explain how you can use the distributive property to write the expression 3x2 6x as the product of a monomial and a polynomial answer as soon as u can?
what rules for ordering computions with numbers does the order of operstions convention provide, why is having an order important
Why do you have to use the order of operations?
We have to use the order of operations so everyone solves a problem the same.
When we use permutation or combination?
Permutation is when order matters, combination is when order does not matter
How many 4 number combinations are there using numbers 1258?
4! = 4*3*2*1 = 24Technically speaking, there are 24 permutations because that is the correct math term when the order matters. Meaning, 1258 is no the same as 1285.In English we commonly use the word "combination" loosely, without thinking if the order of things is important. In math we should be precise. If the order matters, we should call it a permutation. Along those lines, the locks that we commonly call combination locks would really be called permutation locks. That is why I say we use the term loosely.So a permutation is an ordered combination.
How many ways can you choose 5 hearts from a 52-card deck?
there are 13 hearts in all so you would use a combination permutation because order does not matter so 13C5 = 1287
Is how many ways can you choose 4 Cd's from a stack of 8Cd's a combination or permutation?
Any 4 from 8 is a permutation, solved by the use of factorials: 8!/((8-4)! x 4!) which simplifies to (8 x 7 x 6 x 5)/(4 x 3 x 2) ie 70 different ways.
What do you use to compute the total number of a 4-letter names with nonrepeating letters?
permutation without replacement
Is it important to use density instead of mass?
No you should use both cuz they are both important in order to learn about something
How many three digit combinations are there in a 60 digit combination lock?
The "combination" for a lock is actually a permutation, an ordered sequence. So for example: 1,2,3 and 3,2,1 are the same combination, but a different permutation. When opening a lock, obviously the sequence is important, so we want to calculate the permutations. To do that, you multiply the number of possible choices for the first position times the number of possible choices for the second position, etc. Assuming that you can use the same number in all three positions (so 60 to the left, 60 to the right and 60 to the left is a valid choice), there are 60 x 60 x 60 possible permutations, or "combinations" for the lock = 216,000. If you were not allowed to use the same number twice, it would be 60 x 59 x 58 = 205,320. If you could repeat the same number, but not in sequence (so 20, 30, 20 is OK; but 20, 20, 30 is not), then there would be 60 x 59 x 59 = 208,860.
Is there a permutation button on a TI-83 Plus?
Yes. For example, if you want to calculate combination(9,3), press 9 and then press MATH. Use the arrow keys to scroll over to PRB at the top and select nPr. Then press 3. You should see: 9 nPr 3 Press ENTER.
