Suppose that out of 1500 first-year students at ICU, 350 are taking history, 300 are taking mathematics, and 270 are taking both history and mathematics. How many first - year students are taking history or mathematics?

Step-by-step explanation:

Assuming that the 350 taking history and the 300 taking math each includes the 270 taking both history and math, then:

N (H or M) = N (H) + N (M) - N (H and M)

N = 350 + 300 - 270

N = 380

There are 380 first-year students taking history or mathematics.
