Zeke: probability of a dual engine failure on an ETOPS twin

Quoting Zeke (Reply 19):Statistics is based upon probabilities, the chance of a double engine failure on a twin can be as probable as winning the lotto, just about every week someone seems to win lotto.

OldAeroGuy:The regulatory probability of a dual engine failure on an ETOPS twin for a diversion time of more than 180 min. is on the order of one such event in 10 billion flight hours (1 in 10,000,000,000).http://dmses.dot.gov/docimages/p88/436040.pdfAre the odds on your lotto that improbable? If so, the tickets sales required to have a winner must be very high.
