LetE, FandGdenote three events in a random experiment associated with a sample space Q. Express the following events with respect to E, F, G and Q, using set theoretic operations (union, intersection, complement):

1.only E occurs,

2.E and G occur but not F,

3.at least one from E, F and G occurs,

4.at least two from E, F and G occur,

5.both three events occur,

6.none of the three events occur,

7.at most one from E, F and G occur,

8.at most two from E, F and G occur,

9.exactly two from E, F and G occur,

10.at most three from E, F and G occur.
