From where?
Anyways I'll try for the posters sake
Data provided
Demu=X
Boy =Y
Single=Y
Relationship==>X+Y=1
Required to:
{i}Show that why X=1
{ii}Show that why Y=0
Where:
1-engaged &
0-single
Solution {i}
From;
X+Y=1
Then;
X=1-Y...................(i)
But;
Single = Y=0..........(ii)
Substute eqm (ii) into eqn (i)
X=1-0 ==> X=1
Hence verified that girls are always engaged/in relationship
Solution {ii}
From;
X+Y=1 ==> Y=1-X
But; from solution {i} above
X=1
Then;
Y=1-1 ==> Y=0
Hence computed that, boys are always single
