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}
Given:
The equation is:
To find:
The value of y.
Solution:
We have,
On cross multiplication, we get
Dividing both sides by 2q, we get
Therefore, the correct option is A.
the answer is in the photo.
