<PRE><B>Question 426344</B>
What is the probability of selecting a student who liked Chemistry or Biology?                                       
                       Major
Gender    Biology     Anatomy   Chemistry   Total
Male        105         140        47        292
Female      103         25         52        180
Total       208        165         99        472
-----------
Ans: P(chem or biol) = P(chem) + P(biol) = 47/472 + 105/472 = 152/472
