<p>Hello everyone. I am very confused about when to use permutation.
Can you please explain it to me? Thanks.</p>
<p>permutation when order matters, combination when order does not matter/ Welcome</p>
<p>Can ppl please post like individual situations and/or how to do them please?</p>
<p>i.e.</p>
<p>4 digits, first number is a 7 or 4, etc</p>
<p>Permutation= There are 5 people in an election for Prez, VP, and Secretary- any person can get any role, only one person per role</p>
<p>Combination= There are 5 people- 3 will be chosen to be in a committee- there is no order/ranking in this committee, it can be any 3 people</p>
