We have a bag of 20 carrots, all different, and we have to calculate the possible combinations in groups of 9 carrots.

We can calculate this with the formula for combinations (as the order does not matter):

[tex]_{20}C_9=\binom{20}{9}=\frac{20!}{9!(20-9)!}=\frac{20!}{9!11!}=167960[/tex]

Answer: there are 167,960 possible combinatios
