Answer:
The number of permutations is 362880.
Step-by-step explanation:
We can find the number of permutations when sitting around a table by using the Circular Permutation Formula:
[tex]\boxed{P_n=(n-1)!}[/tex]
where:
Given n = 10 ("you and your 9 friends" makes a total of 10 people), therefore:
[tex]P_n=(n-1)![/tex]
[tex]P_{10}=(10-1)![/tex]
[tex]=9![/tex]
[tex]=362880[/tex]
