Hello everyone, Thank you for your sharing information, I think I found the right answer, but I am not really sure why it is right. net torque = (75)(9.8)3sin30 + (10)(9.8)2.5sin30 - 4.33F3 = 0 1102.5 + 122.5 - 4.33F3 = 0 F3 = 282.9 N The part I don't understand is (4.33)(F3). why does r = 4.33? Tha...

Can someone explain to me the key difference as to why the Combination and permutation formulas are different by n!

Combination=
C(n,r)=n!/(n-r)!

Permutation=
P(n,r)=n!/n!(n-r)!

Any help would be very beneficial for me.

Thanks and Regards

Hey friends.

Very few things have been solved in mathematics, and there are even fewer things that we understand, Factorial means multiple all the integers up to the number given, starting at 1. 0!=1 by convention.

2*2*3*4*5=240

Thanks a lot again
