Twenty-two percent of all light emitting diode (LED) displays are manufactured by Samsung.
What is the probability that in a collection of two independent LED HDTV purchases,
at least one is a Samsung? (Round your answer to 3 decimal places.)
~~~~~~~~~~~~~~~ 

The probability that no one of two diodes is a Samsung is  %281-0.22%29%5E2 = 0.78%5E2 = 0.6084.


The answer to the problem's question is the COMPLEMENT to 1  

      P = 1 - 0.6084 = 0.3916 = 0.392  (rounded).

Solved.
