From Medium:

I claimed a 37% lifetime chance based on raw historical data, and caught flack, but the consensus among those particular risk analysis professionals is around 35% in the next decade. Let’s unpack that incredible figure for a second, with a little mathematics. I derived my 37% lifetime estimate based on an annual chance of 0.59% per year. If their 35% chance per decade estimate is accurate, using the same math (as done before, but backwards), they’d be looking at a 4.3% chance per year. Mr. Mines thinks it’s bigger.
