Solving (5): E and F
Sets of E and F = E n F

List out common elements

<em>They are not mutually exclusive because </em>
<em />
Solving (6): F and G
Sets of F and G = F n G

List out common elements

<em>They are not mutually exclusive because </em>
<em />
Solving (7): F or G and P(F or G)
Sets of F or G = F U G

List all elements without repetition

Solving P(F U G)



Hence;
