A mass extinction would require a very unlikely event such as a major cosmic collision.
Even the major extinction event that killed the dinosaurs 65,000,000 years ago left about 1/3 of all species intact. It might require something really, really big, like the collision that created the moon nearly 4,000,000,000 years ago. So, let's say 4 billion to one, at least for this year.
