A shelf has books with different colored covers; 5 are blue; 6 are red; 1 is orange; 3 are white
and 1 is blue and white. What is the probability of choosing a book that has either orange or white on its cover?
~~~~~~~~~~~~~~~ 

"Either orange or white"  means  "orange or white, but not both at the same time".


Therefore, the calculation is as follows


    P = %281%2B3%2B1%29%2F%285%2B6%2B1%2B3%2B1%29 = 5%2F16.      ANSWER

Solved.

" Either . . . or "  is called  " OR exclusive "  as opposite to simple  " or ",  which is  " OR inclusive ".
