A survey was conducted among 20 students of a Secondary School of class X, where 14 students participated in football and 12 students in volleyball games. Every student has participated in at least one game.

1. Assuming the set of students who participated in football as F and volleyball as V, write the cardinality of the set of students who participated in volleyball or football.
2. Present the above information in the Venn diagram.
3. Find the number of students participating in exactly one game by using Venn diagram.
4. If two students who respond only to football are unable to play the game due to health problems, the cardinality of which set is changed? Give reason.
