Alison has five different hats, six different bracelets, and seven cats. She wants to take a selfie with a hat, a bracelet, and two cats. How many different selfies can she take?

Can someone please explain to me these problems?

1. 2 B's and 2 C's repeat, so the total number of possible ways to arrange it is \(\frac{6!}{2!*3!}=\boxed{60}.\)

2. I think the answer is \(\binom{5}{1}*\binom{6}{1}*\binom{7}{2}=\boxed{630}. \)
