Answer: There are 495 different ways.

Step-by-step explanation: I took the FLVS test. Since it's a combination, the order doesn't matter, so it's 495, not 11880.

Answer:

b. 11,880

Explanation:

You can choose 1 out of 12 for the first one.

12 ×

Then, you choose 1 out the remaining 11 for the second one.

12 × 11

Then there are 10 left for the third and 9 left for the 4th.

12 × 11 × 10 × 9 = 11,880

Answer: 11,880
