A two-engine plane will land safely if at least half of it’s [sic] engines function properly. The probability that each
engine functions properly is 80%. Determine the probability of a safe flight on this plane.
----------------
The probability of failure is 20% = 0.2
The probability of 2 failures is 0.2*0.2 = 0.04
--------------
--> 96% probability of a "safe flight."
-------------
The landing is the part of the flight that's important.
---------------
PS it's = it is
