Problem B3
arpanshah
I got (14 choose 12) + (17 choose 12) + (31 choose 12). Are each of the cases multiplied or added? Can anyone verify this? Thanks!

Yup! you would add them because they are different cases

Wouldn't you need to multiply that whole answer by (3choose1)? to account for choosing a flower shop?
