Answer:
275 yards of ribbon need to be ordered
Step-by-step explanation:
Figure out how much ribbon, in inches, is needed altogether by multiplying the amounts of ribbon by how many boxes are expected to sell for both box sizes:
Small Boxes:
20 in • 225 boxes = 4500 in of ribbon needed
Large Boxes:
30 in • 180 boxes = 5400 in of ribbon needed
Add it up to see how much you need:
4500 + 5400 = <u>9900 in of ribbon needed in total</u>
<u />
There are 36 inches in 1 yard, so divide 9900 by 36 to see how many yards need to be ordered:
9900 ÷ 3 = 275 yards
(Alternatively, you could divide 9900 by 12 inches in a foot to get 825 feet. Then you would divide 825 by 3 feet in a yard to get 275 yards)

Step-by-step explanation:
The quick way to get the answer is just type "42 choose 11" into Google.
Or if you want to figure it out yourself, you have 42 choices for the first potential juror, 41 choices for the second potential juror, etc.
Now before you stop there, you only care about the combination of the 11 people chosen, not what order they are selected, so you need to divide by the ways to arrange 11 people.
Final expression:
C(42,11) = (42 * 41 * 40 * 39 * 38 * 37 * 36 * 35 * 34 * 33 * 32) / (11 * 10 * 9 * 8 * 7 * 6 * 5 * 4 * 3 * 2 * 1)
