The following table summarizes the results of the survey.
a. What is the probability that {{{highlight(cross(the))}}} <U>a</U> student has blue eyes?
b. What is the probability that {{{highlight(cross(the))}}} <U>a</U> student is {{{highlight(a)}}} male?
c. What is the probability that {{{highlight(cross(the))}}} <U>a</U>  {{{highlight(cross(students))}}} <U>student</U> {{{highlight(cross(have))}}} <U>has</U> green eyes or {{{highlight(is)}}} a female?

<pre>
Start calculating total number of all students.
My help is not needed for it.


(a)  From the table, find the number of students having blue eyes (favorable set).
     Remember that you should add blue-eyed males and blue-eyed females. 

     To find the probability, divide favorable by total.



(b)  From the table, find the number of males and relate it to the total.



(c)       all females + green-eyed males
     P = --------------------------------- .
                    total

Happy calculations !
