'If you flew, say, 10 times a year rather than 365.25, all on the 737 Max, it's a fraction of a percent chance.'

This works out to around 0.2% (1 in 2000) which is spectacularly poor odds for modern aviation where the typical risk of a crash on a single commercial airliner is around 1 in 5 million (less than 1 in 100 000 for 10 flights per year over 50 years - so basically 50 times less safe).
