Corrected Question

Points X and Y are endpoints of a diameter of Circle W. Point Z is another point on the circle. Find the probability that
\angle XZY is a right angle.

Answer:

Probability=1

Explanation:

Theorem

  • If an Inscribed angle intercepts a semicircle, the angle is a right angle.

Given that X and Y are endpoints of a diameter of Circle W and point Z is on the circle's circumference.

I have prepared a diagram which is attached.

Then,
\angle XZY is an angle which intercepts a semicircle.

By the theorem above,
\angle XZY is a right angle.

Therefore, the probability that
\angle XZY is a right angle =1
