If I have 12 (indistinguishable) plain cookies and 1 chocolate chip cookie, how many ways can I put the cookies on my Grandma's 4 x 3 tray? The most cookies you can put on it is 12.

 

plz help.

We can put the  1 chocolate chip anywhere   = 12 ways

Since the plain are indistinguishable.......they don't matter

 

So.....12 different  ways

 

cool cool cool
