A college class is composed of 42 students, 20 are taking Earth Science, 23 are taking Philippine History, 17 are taking algebra, 12 are taking Earth Science and Philippine History, 9 are taking Earth Science and Algebra, 7 are taking Philippine History, and 5 are taking all the three subjects.

a. How many are taking Algebra only?

It's really confusing because " 23 are taking Philippine History" was mentioned first, then "7 are taking Philippine History"

sori, 7are taking both Philippine History and Algebra.

OKay :)

b. How many are taking Algebra and Earth Science but not Philippine History?

c. How many are not taking the three subjects?
