Getting back to the original question...

Twin-engine turbine powered commercial aeroplanes have an "in-flight
propulsion system shutdown rate" of approx 0.02 per 1000 hours.
(Source: ICAO ETOPS approval papers)

You will have to work the rest out. That's all I can help you with.

That's just the minimum standard that 180-minute ETOPS certified
aircraft need to meet. In actual practice, engines exceed this
standard.

To get the rate on aircraft level, you have to square the single engine
IFSD rate and multiply it with the average flight length for the
aircraft type.
