Lauri is picking out material for her new quilt. At the fabric store, there are 1919 solids, 99 striped prints, and 1212 floral prints that she can choose from. If she needs 33 solids, 33 floral prints, and 33 striped fabrics for her quilt, how many different ways can she choose the materials

1,79,07,120  ways

Step-by-step explanation:

Ways in which 3 solids can be chosen from 19 solids = 19 c 3

33 striped prints can be chosen from 99 striped prints in 9 c 3 ways

33 floral prints can be chosen from 121 floral prints in 12 c 33 ways

So, total ways = (19 c 3) (9 c 3) (12 c 3)

(969) (84) (220)

1,79,07,120

341

step-by-step explanation:

all you have to do is 9x31 (which equals 279) and then 20x31 (which equals 620). then you have to subtract. 620-279=341.
