if you mean 7c^4/7p^4, then it'd just be c^4/p^4. Otherwise, I have no idea lol.
OpenStudy (anonymous):
by the combination
OpenStudy (m):
7c4 = 7!/(7-4)!4!
OpenStudy (m):
7p4 = 7!/(7-4)!
OpenStudy (anonymous):
7!(3!)4!

OpenStudy (m):
yeah
OpenStudy (anonymous):
because it says leave it as a fraction or an integer
OpenStudy (m):
35/840 or .04166
OpenStudy (m):
it's the correct answer :)
OpenStudy (m):
fraction or an integer is a contradiction

OpenStudy (m):
your teacher meant fraction or decimal
OpenStudy (anonymous):
so leave it as a fraction or put the .04166
OpenStudy (m):
either is fine but fraction is better because it's more accurate
OpenStudy (m):
use fraction
OpenStudy (anonymous):
Ok I just have one last similar one
