Geometric Probability M217 - Geometry Refresh… Probability - The chance that an event will occur (a # between 0 and 1). Geometric Probability – Probability involving geometric measures, such as length or area. Probability and Length Length of CD P(point K is on CD ) = Length of AB A C D B Probability and Area P(point K is in region M) = J M Area of M Area of J Example F 0 R 1 2 3 E 4 5 6 7 M 8 D 9 10 11 12 Find the probability that a point K, selected randomly on FD , is on the given segment. 1.
