VOCAB TO KNOW

Geometric Probability:Probability that involves a geometric measure such as length or area.

LENGTH

If a line segment (1) contains another segment (2), and a point on the segment (1) is chosen at random, then the probability that the point is on the segment (2) is

Length of the segment (2)

Length of the segment (1)

AREA

If a region A contains a region B and a point E in region A is chosen at random, then the probability that point E is in region B is

area of region B

area of region A
