Abalone are colorful shell fish found throughout the world. When an abalone shell is found, it can be classified as either Male (M), Female (F), or Infant (I). Collectors can usually guess if an abalone is M, F, or I based upon measurements taken of the shell.

Assume that a collector finds an abalone shell with the following measurements in centimeters.

LENGTH = 11
DIAMETER (DIAM) = 11
HEIGHT = 3.5
RINGS = 10
Assume a collector has the following decision tree. What is the probability that the abalone is a Male (M)?
