A : When both father and mother are left handed :
Chances of left handed child is24 % .
B : When father is right handed and mother is left handed :
Chances of left handed child is22 % .
C : When father is left handed and mother is right handed :
Chances of left handed child is17 % .
D : When both father and mother are right handed :
Chances of left handed child is 9\%.
Assuming thatP ( A ) = P ( B ) = P ( C ) = P ( D ) =
and L denotes the event that child is left handed.
Based on the above information, answer the following questions :
(i) FindP ( L ∕ C )
(ii) FindP ( L ∕ A )
(iii) (a) FindP ( A ∕ L )
OR
(b) Find the probability that a randomly selected child is left handed given that exactly one of the parents is left handed.
