Not really necessary. The two accidents killed everyone on board, and it was a typical load. The number I estimated is something like "fatal crash for everyone per mile". You could multiply by average of passengers on each flight and divide by the average number of passengers on the deadly flights to get a slightly more accurate risk, but not much would change.
