Hey,

I have two destroyer questions if anyone has any input.

Gen Chm 87: I understand transition metals are likely to be colored, but isn't Ag a transition metal as well? So wouldn't AgCl have the possibility to be colored?

Math #86. I actually never learnt permutation questions and stuff of that sort so its all new to me. But why are we not using the formula in this question:

N!
___
K! (N-K)!
