Which statement is true? you can use both permutations and combinations when order matters. you can use permutations when order matters and use combinations when order doesn’t matter. you can use permutations when order doesn’t matter and use combinations when order matters. you can use permutations and combinations when order doesn’t matter.

Step-by-step explanation:

The correct statement is that you can use permutation when order matters and use combination when order does not matter.

Permutation is applied to objecys when we want to arrange objects in a specific way. It talks about the number of ways several objects can be arranged taking some particular objects at a time.

If n people are to be arranged in r manner, this can be expressed as;

nPr = n!/(n-r)!

Combination has to do with number of ways a set of numbers r can be selected out a pool of numbers n. Mathematically, if r numbers are to be selected from total numbers of n people, this can be expressed as;

nCr = n!/(n-r)!r!

points are handed out whenever you post answers.

brainliest answers are handed out by the person asking the question, so whether your answer is picked depends entirely on whether the asker bothers to pick

if you're asking about your rank, it depends on having a certain number of points and a certain number of brainliest answers. for example, at the time of this writing, i have 44338 points out of 15000 needed for the next (nearly triple the requirement! ) but i only have 24 out of 50 required brainliest answers. this number decays, meaning after a certain amount of time (i think about a month), the total number of brainliest answers you've earned doesn't count toward this total. (i've been stuck at the same rank for a long

the lesson to learn here is that you shouldn't worry about points or rank. chances are, no matter how good an answer you may provide, your efforts will go mostly unnoticed unless you focus on the newest/most active questions that get posted.
