Question
Spiral Review A vegetarian restaurant offers 52 vegetarian meals on its menu. Four of the meals include eggplant. Shan picks a dish at random from the menu with his eyes closed. What is the probability that he orders a meal that does not include eggplant? Write the probability as a fraction.

place r′ so that qr′ is parallel to the tangent.

now we get that ∠r′py=∠pr′q, where y is on the tangent, on the opposite side of p from x.

also, because of the symmetry, ∠r′py=∠qpx.

finally, note that no matter where we place r, as long as it's on the correct arc, we have ∠prq=∠pr′q.

stringing all these equalities together, we end up with ∠prq=∠qpx.

this picture will show how its going to look like.
