I have some questions. In 9.25, how would you put the gray into consideration? By multiplying the total arrangements of the want by two? 

In 9.26, I feel like I know Pr 7 by "common sense"... Idk what to do.

For 9.30, I got everything down (using stars and bars and the equation (n-1) choose (k-1) except for the none of the rolls are 1 part. 

Also, 0 is an even number right?
