Answer:

The answer is 455 ways.

Step-by-step explanation:

If adding only twelve, you must leave out three of the fifteen, and the number of ways is: = 15! / (3! * 12!).

1∗2∗3∗4∗5∗6∗6∗8∗9∗10∗11∗12∗13∗14∗15 over

(1∗2∗3)∗(1∗2∗3∗4∗5∗6∗6∗8∗9∗10∗11∗12) =

13∗14∗15 over

(1∗2∗3)

27306 = 455

Or:

15! / (3! * 12!) = 455.

Best of Luck to you!
