N is the variable, you solve by subtracting 6 from 20, getting n = 14.
The answer is "alternate exterior angles theorem."
<span>Thus, simply compute the probabilities for 4,5,6,7 as well, and then add. Alternatively, you can compute the probabilities for 0,1,2 correct answers, and subtract the total from 1, giving the same result. </span>
