Here is the Venn diagram.....as you can add up...there are only 142 students in the diagram....that means 8 do not like any of the subjects

Math only = 15     English only = 42   History only = 25

Using the Principle of Inclusion and Exclusion, we have \(63+85+62-31-25-20+8=142\) students. Thus, eight of them like neither of the three subjects.

 

Math Only: 63-31-25+8=7+8=15 students.

 

English Only: 85-31-20+8=42 students.

 

History Only: 62-25-20+8=25 students.
