The positive cases aren't a representative sample, as has been said 30 times in this thread. So line 3 is bad statistical reasoning, and completely invalidates their conclusion.

The only people who are getting tested are those who believe they have symptoms. This is beginning to change as we get more tests, and as a result, the % infected by their reasoning is decreasing day by day.

The math does not reflect reality. Why do you think 12% of Californians have covid? What impact does that have on the chance of dying stat?

Also, I fixed the space on the fourth line.
