See a solution process below:

Explanation:

Because of the information in the problem we can see that:

#56% + 32% = 88%# Buy Milk and Fruit.

However, because 22% by both we need to subtract this from the number giving:

#88% - 22% = 66%# of the students buy Milk and/or Fruit.

This means:

#100% - 66% = 34%# buy neither.
