Re: Permutations and Combinations
The two questions look easy enough that I think you should be able to do them yourself. The answers are 4! and 1 respectively. By the way, Chetah: are you just posting your homework questions and asking us to do your homework for you? Its all very well copying the solutions we give but its much more important to understand the working behind the solutions we post.

Re: Permutations and Combinations
These are not my assignments, they are questions I have worked out and checking my answers. Would you like me to post my solutions?
