I had said: "The news this morning mentions that there had been 6 crashes in the past one week. The latest one follows just one or two days after all military flights were suspended for a day in order that persons involved could ponder the situation. "Is there a mathematician here who could calculate the odds that this is due to "chance," given a reasonable figure for the average number of such crashes per year?" I read today that the U.S. moratorium on military training flights hasn't yet taken place, but will do so on Monday. And it turns out it doesn't take a real mathematician or statistician to calculate the odds of this having occurred due to random chance. I don't know how many crashes per year we typically have. Let's say it's 36.5 crashes, to make the arithmetic simpler. Then the odds of a crash occurring on any one day of the year is 0.1, or 36.5/365. So if you had 6 crashes on successive days, the odds for that would be 0.1x0.1x0.1x0.1x0.1 = 1/100,000. (One doesn't count the first crash, which initiated the string.) The odds of not having a crash on any one day is 0.9. So if you had 6 crashes in 7 days, with no crash on the 4th day, say, the odds for that would be nearly the same: 0.1x0.1x0.9x0.1x0.1x0.1, or 1 in 90,000. These are pretty slim odds, though you'd expect it to happen one time in about 247 years (247 being 90,000/365). This is rare enough to make one suspect some sort of sabotage. But I don't know if the 36 crashes per year figure is in the right ballpark or not. Jim Deardorff
