We will see that 451 students take at least one of the two clases, then the correct option is C.

Which number of freshmen takes at least one of the two classes?

We know that there are a total of 480 freshmen.

  • 333 of them, take algebra.
  • 306 of them, take biology.
  • 188 take both.

The total number of students that take at least one is equal to the sum of the numbers of students that take algebra and the number of students that take biology minus the number of students that take both (because we are adding these twice). This gives:

N = 333 + 306 - 188 = 451

451 students take at least one of the two classes, so the correct option is C.
