Answer:
Step-by-step explanation:
U= {A,B,C,D,E,F,G}
X = {A, B, C, D}
Y = {A, C, E, F}
a) X or Y = {A, B, C, D} and {A, C, E, F} = {A, B, C, D, E, F}
B) X and Y = {A, B, C, D} or {A, C, E, F} = {A, C}
c) Complement of X = {A,B,C,D,E,F,G} - {A, B, C, D} = {B,D,G}
Element in the given sets will be [tex]\left \{ A,B,C,D \right \}[/tex] and [tex]\left \{ A,C,E,F \right \}[/tex]
Given information,
A tile is selected from seven tiles, each labeled with a different letter from the first seven letters of the alphabet.
X: The letter selected comes before "E".
Y: The letter selected is found in the word "FACE".
The outcomes in favour of X will be:
[tex]X=[/tex] [tex]\left \{ A,B,C,D \right \}[/tex]
The outcomes in favour of Y will be:
[tex]Y=\left \{ A,C,E,F \right \}[/tex]
Therefore,
Element in the given sets will be [tex]\left \{ A,B,C,D \right \}[/tex] and [tex]\left \{ A,C,E,F \right \}[/tex]
