Unfortunately, I don't remember where I found the exact statistic, but I do remember that when that EgyptAir 767 went down, I heard the following:

Total number of cycles (takeoffs and landings) for all 767's since their inception: 3,000,000.

Total number of 767 hull losses since their inception: 3 (including EgyptAir).

Ratio: For every one million 767 flights, +1+ flight crashes.

One in a million...that seems pretty safe to me.
