Question
The survey involved 61 students in a classical music lecture class with the following preferences: 

- 35 students like Wolfgang Amadeus Mozart
- 34 students like Ludwig van Beethoven
- 30 students like Franz Joseph Haydn
- 13 students like both Mozart and Beethoven
- 21 students like both Mozart and Haydn
- 8 students like all three composers

To analyze these results, a Venn diagram is used. The sets are defined as follows:

- M represents students who like Mozart.
- B represents students who like Beethoven.
- H represents students who like Haydn.

**Venn Diagram Explanation:**

The Venn diagram shows three intersecting circles, each labeled with M, B, and H, representing the students who like each composer. Each intersection represents various combinations of preferences:

- The central intersection of all three circles includes students who like all three composers (8 students).
- Intersections between two circles, excluding the central one, represent students who like two composers. 
- The non-overlapping sections of each circle represent students who like only one composer.

**Questions:**

(a) How many students like exactly two of these composers?

(b) How many students like exactly one of these composers?

Students need to use the information provided to fill out the Venn diagram and answer questions (a) and (b) based on the intersecting circles.
