An elementary school is offering two optional language classes, one in French and the other in
Spanish. These classes are open to any of the 120 upper-grade students in the school. Suppose
there are 32 students in the French class, 36 in the Spanish class, and a total of 8 who are in
both classes. If an upper-grade student is randomly chosen, what is the probability that this
student is enrolled in at least one of these classes
~~~~~~~~~~~~~~~

The total number of upper-grade students is 120.


The number of those who learn at least one of the two languages is  32 + 36 - 8 = 60.


Therefore, the probability that the randomly chosen upper-grade student is enrolled in 
at least one of these classes is


    P =  =  = 0.5 = 50%.     ANSWER

Solved.
