Many scientists claim that the lowly chicken is the closest living relative to theTyrannosaurus Rex. (Oh how the mighty have fallen.)

Assume the following made up numbers are true. (They are not.)

A chicken has a 10% chance of laying a white egg and a 90% chance of laying a brown egg.

• White eggs have a 93% of hatching into chicken and a 7% chance of hatching into aT. rex.
• Brown eggs have an 82% chance of hatching into a chicken and an 18% chance of hatching into aT. rex.

AT. rexhatches from an egg. What is the chance that it hatched from a white egg?
