Question

In a class of 50 student 30 students like math 25 students like science and 16 like both find the number of students who like either math or science

Answer 1

Answer:

Step-by-step explanation:

30 students like maths.

25 students like science.

So 30 + 25 is the number of students who only like maths or science and students who both like math and science.

But 30 contains the number of students who both like maths and science, and 25 do the same thing.We compute the number of both twice

So 30+25–16*2=23 is the number of students who only like maths and science.

And you can compute it another way: 30 contains students who like science ,you can minus 16 is the number of students who only like maths , the same way, 25 minus 16 is the number of students who only like science, and we plus them to get the result:(30–16)+(25–16)=23.
