10 names in a hat — odds that no one picks themself?

I have an annual tradition where 10 names are placed in a hat, and those same 10 members randomly select one at a time. If anyone selects their own name, the entire process restarts.
What are the odds that all 10 people select a name that is NOT themself?

This is a derangement problem. Did you mean probability rather than odds?

Yes, I suppose probability would be the correct term here. Given the conditions described above, how would that be calculated?
