Question 1190738: 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 Answer by ikleyn(52781) (Show Source):

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
