The answer to this is 67 / 450
We know that:
Experimental probability = number of positive results / number of experiments
So the Experimental probability = 67 / 450
A ) S n = ( n - 2 ) · 180°
b ) The measure of each angle:
α = ( n -2 ) · 180° / n
c ) Sum of all exterior angles: 360°
d ) The measure of each exterior angle:
α 1 = 360° / n
e ) ( n - 2 ) · 180° / n + 360° / n =
= ( 180° n - 360° + 360° ) / n = 180° n / n = 180°
It makes sense because:
α (interior angle)+ α 1 ( exterior angle ) = 180°
