Question 1202108
.
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 blue or white on the cover?
~~~~~~~~~~~~~~~~~~~~


<pre>
"Either blue or white"  means  "blue or white, but not both at the same time".


Therefore, the calculation is as follows


    P = {{{(5+3)/(5+6+1+3+1)}}} = {{{8/16}}} = {{{1/2}}}.      <U>ANSWER</U>

Solved.
