A = {1,2,3}
B= {a,b,c}
c = {x,y,z}
R = {(1,a) (2,c) (3,a) (3,c)}
S = {(b,x) (b,z) (c,y)}
Find RoS (composition of relation)my solution was this:
(2,c) belongs to R and (c,y) belongs to S so (2,y) belongs to RoS
(3,c) belongs to R and (c,y) belongs to S so (3,y) belongs to Ros
RoS={(2,y) 3,y}
can we use (c,y) more than one time..
Is this correct answer ??
