Total number of balls = 5+6+6=17
P(RR)=Probability of two reds
=(5/17)*(4/16)
P(WW)=(6/17)*(5/16)
P(BB)=(6/17)*(5/16)
Probability of two same coloured balls
=P(RR)+P(WW)+P(BB)
P(RR)=Probability of two reds
=(5/17)*(4/16)
P(WW)=(6/17)*(5/16)
P(BB)=(6/17)*(5/16)
Probability of two same coloured balls
=P(RR)+P(WW)+P(BB)
