Vedclass · Answer

(A) The sex of a child is determined by the combination of sex chromosomes at the time of fertilization. Each pregnancy is an independent event. The probability of having a male child $(XY)$ or a female child $(XX)$ is always $1/2$ or $50\%$,regardless of the sex of the previous children. Therefore,the probability that the eighth child will be male remains $1/2$.

If the first seven children born to a specific couple are all male,what is the probability that the eighth child will also be male?
