Question 1202098
.
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? 
~~~~~~~~~~~~~~~


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


Therefore, the calculation is as follows


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

Solved.


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