Question 1196867
.
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.)
~~~~~~~~~~~~~~~


<pre>
The probability that no one of two diodes is a Samsung is  {{{(1-0.22)^2}}} = {{{0.78^2}}} = 0.6084.


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

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

Solved.
