In this lesson our instructor talks about geometric probability. First she discusses length probability postulate and area probability postulate. Then she talks about are of a sector of a circle. Four complete extra example videos round up this lesson.
Length Probability Postulate: If a point on AB is chosen at random and C is between A and B, then the probability that the point is on AC is AC/AB
Area Probability Postulate: If a point in region A is chosen at random, then the probability that the point is in region B, which is the interior of region A, is the area of B to the area of A
Area of a Sector of a Circle: A sector of a circle is a region of a circle bounded by a central angle and its intercepted arc. Area = (central angle)/(360 degrees) × πr2
