most of the questions i will post i have the answer... but i dont know how to set up the problem to solve it??
for this i would have done 7 C 6 however, the answer is actually 5040??
but isn it asking for combinations? i think my teacher made the answer key wrong
here all letters have to be used
if we put any letter at 1 out of 7, then we are left with 6 letters only to fill the second spot. and so on
lordofpens, the term "combination" is sometimes a bit murky Think of a locker. The "combination" lock is really a permutation lock because order matters. Something like 347 is different from 743. And yet, somehow "combination lock" has stuck instead of "permutation lock"
will that change the answer?
you need to compute 7 P 6 instead of 7 C 6
ohh ok. i guess the "combination" in the sentence is misleading
in that case 7*6*5*4*3*2=? answer is still the same.
