An experimental serum was injected into 500 guinea pigs. Initially,
200 of the guinea pigs had circular cells, 100 had elliptical cells, and
200 had irregular cells. After the serum was injected,
none of the guinea pigs with circular cells were affected, 500 with elliptical cells were affected, and all of those with irregular cells were affected. Determine the empirical probability that a guinea pig with (a) circular cells, (b) elliptical cells, and (c) irregular cells will be affected by injection of serum. I give brainest for right answer only
