c.electroplating
d.to increase the sensitivity of galvanometer
As we increase number of trials, the difference between theoretical and experimental probability reduces. As the number of trials are increased than experimental probability move towards theoretical probability. If a coin is flip 10 times and we get head 6 times than experimental probability is 0.6.
