Dogsare inbred for such desirable characteristics as blue eye color; but an unfortunate by-product of such inbreeding can be the emergence of characteristics such as deafness. A 1992 study of Dalmatians (by Strain and others, as reported inThe Dalmatians Dilemma) found the following:

(i)31% of all Dalmatians have blue eyes.(ii)38% of all Dalmatians are deaf.(iii)42% of blue-eyed Dalmatians are deaf.

What is the probability that a randomly chosen Dalmatian is blue-eyedanddeaf?
