Answer 1

<b>Your vocabulary is incorrect. Please call this to your math and English teachers' attention.</b>

This is what you mean:
<i>In a class of 42 students, 25 <b>take</b> biology, 15 <b>take</b> history, and 18 <b>take</b> biology but not history.
i. Draw a Venn diagram to show the information.
ii. Find how many students <b>take</b> neither history nor biology.</i>

Answer 2

After making your Venn diagram, you realize that we don't know how many take
both biology and history, label that part x
Now label the part of only biology as 25-x

but you are told: 25-x = 18
x = 7
Now you can fill in the rest of the VD, and you would have "only history" as 8
Add up all the parts of your diagram and compare it to the total of 52
How many take neither of the two subject ?
