The answer is B. 10 vertices because it all depends on the edges. You have to subtract the edges by faces/vertices to get your faces/vertices so 20-12 is 10 so you are correct
The answer is 62/95. You determine this by calculating the probability of both students being girls.
Probability first student is girl: 12/20
Probability second student is girl: 11/19
Multiply 12/20 * 11/19 = 132/380 or 0.347
Probability of both students not being girls: 1 - 0.347 = 0.653 or 62/95
Well, an interior angle plus an exterior angle has to equal 180°. Also, the sum of the interior angles is represented by this formula: [-2 + n]180, whereas the sum of the exterior angles all add up to 360°, and is represented by this formula: 360/n [let "n" represent the number of sides in every polygon].
