Given:

- n(Students) = 150
- n(Math) = 85
- n(English) = 70
- n(Math and English) = 50

n(Math) = n(Math only) + n(Math and English)

85 = n(Math only) + 50

**35 = n(Math only)**

**n(Math and English) = 50**(given in problem statement)

n(Neither Math nor English) = n(Students) - (n(Math) + n(English) - n(Math and English))

n(Neither Math nor English) = 150 - (85 + 70 - 50)

n(Neither Math nor English) = 150 - 105

**n(Neither Math nor English) = 45**

Sorry, can't draw a Venn diagram with this text editor.
