If nondisjunction of the two X chromosomes occurs during oogenesis, then some eggs will have two X chromosomes and some eggs with no X chromosomes. If a normal sperm fertilizes these two types of eggs, what genotypes are possible?

If the sperm was carrying a Y chromosome they would be XXY and one only having a Y (which is fatal). If the sperm was carrying an X they would be XXX (superwoman) or just and X (which is not fatal).
