A = {1,2,3}(adsbygoogle = window.adsbygoogle || []).push({});

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 ??
