The junior class has 50 students. fifteen students take only french, 5 students take only latin, and 10 take both. if a student is chosen at random from the class, what is the probability that the student chosen takes french?

10a^3+277a^2-132a-792

step-by-step explanation:

(2a+11)(5a-12)(foil)

=10a^2-24a+55a-132 =10a^2+31a-132

(10a^2+31a-132)(a+6)

=10a^3+60a^2+31a^2+186a^2-132a-792 =10a^3+277a^2-132a-792
