3.If Megan and Eric have three children, what is the probability that at least one of them will have Huntington’s disease? Round to the nearest tenth of a percent.--each kid has same chance
4.If Megan and Eric have two children, what is the probability that at least one of the will have Huntington’s disease? Round to the nearest tenth of a percent.--each kid has same chance

Your first two answers are correct. However, the 3rd and 4th questions ask what is the probability that one of their children will have the disease. You're right that each child has the same chance -- 1 of 4. But the more children this couple has, the more chances are that at least one child will have the disease.
