If annual occurence is 2 and it happens twice every week in a year.
But it has not so far :)
Weekly occurence of 0 has 13.5% chance of happening this being the case for 7 weeks before this last 8th 2021, 13.5*7/8= 11.8% so far.
But I'm no statistician.
- jojobas 6y agoI've run the numbers here https://stattrek.com/online-calculator/poisson.aspx https://stattrek.com/online-calculator/poisson.aspx At a weekly probability of 0.04 (2 failures/52 weeks) the probability of 2 failures within a week is 0.077%. The probability of 0 failures in a week is 96%. Accounting or halving of flight frequency it's 0.02% and 98% respectively.
- raws 6y agoOh right k for a week is not 2 but 2/52!
