Answer:

45

Step-by-step explanation:

Since the order does not matter in this situation, this is a combination.

Use the combination formula, , to find the number of combinations. Only 8 of the 10 flowers can be used to fill the 8 flowerpots. Therefore, n = 10 and r = 8.

10C8= 10!/8!(10-8)! (sub)

= 10!/8!2! (subtract)

= 3628800/(40320)(2) (evaluate)

= 3628800/80640 (multiply)

= 45 (divide)
