Hello!

I am in the Math Challenge WInter 2016-2017 II-B Combinatorics class. 

On F7 of homework 5, is there a front and back cover for each book, or just one cover? If there are 2 covers for each book, can the covers be different colors?

Thank you,

Sophie Zhu

Also, for P5, do all the integers have to be different (e.g. could a sequence be something like 100, 101, 100, ...)? Thanks!

Also, on P6, part b, do we actually have to 1) only explain, 2) explain and show work (to get answer), or 3) only show work?

Hi Sophie,

Thanks for your questions!

For F7:  Each book has a single cover.

For P5:  The sequences can have repeated integers.

For P6:  You should show your work for the easier method (and explain why this method works). There is not much work that needs to be shown, but a little explanation is needed as to why the method works.

Best,

John
