a)from given diagram
P(Blue eyes |red hair) =0.473 (this is probability that a Caucasian child will have Blue eyes if he/she has red hair)
P(blue eyes and red hair) =P(red hair)*P{blue eyes |Red hair) =0.025*0.473 =0.011825
this is probability that a Caucasian child has both blue eyes and red hair.
b)
P(freckles |red hair and blue eyes) =0.857
(this is probability that a Caucasian child will have freckles if he/she has red hair and blue eyes both)
P(freckles and red hair and blue eyes) =P(red hair and blue eyes)*P(freckles |red hair and blue eyes)
=0.011825*0.857 =0.010103
(this is probability that a Caucasian child has each of freckles, blue eyes and red hair.)
