Candace has 4 trophies to place on a shelf. How many possible arrangements of all 4 trophies are there?

OpenStudy (mackenzie2013):

4c4? huh? Is that multipy?

rvc (rvc):

wait wait the first trophy has 4 chocies the second trophy has 3 chocies

rvc (rvc):

so it would be 4 X 3 X 2 X 1

rvc (rvc):

since after a trophy is placed one place would be filled

rvc (rvc):

@UsukiDoll :)

OpenStudy (mackenzie2013):

This is confusing me haha

rvc (rvc):

suppose we have four trophies namely A B C and D and four places namely 1 2 3 4 now let trophy B occupy place no 3

OpenStudy (usukidoll):

statistics and probability ... <--- this user is not an expert at this topic

rvc (rvc):

so now we are left with : Trophy : A C D Place : 1 2 4 now trophy A can occupy any one the three places from 1 2 4

rvc (rvc):

so first trophy B had 4 choices AND trophy A has 3 choices

rvc (rvc):

are you getting the explanation?

OpenStudy (mackenzie2013):

Its still confusing the H-E double hockey sticks out of me.
