Vedclass · Answer

(C) The determination of the sex of each child is an independent and mutually exclusive event.In humans,the sex of the child is determined by the sex chromosomes of the father $(XY)$ and the mother $(XX)$.During fertilization,there is a $50\, \%$ chance that the sperm carrying the $X$ chromosome will fertilize the egg,resulting in a girl,and a $50\, \%$ chance that the sperm carrying the $Y$ chromosome will fertilize the egg,resulting in a boy.Therefore,regardless of the gender of the previous children,the probability of having a girl in the next pregnancy remains $50\, \%$.

$A$ couple has $6$ children-$5$ are girls and $1$ is boy. The percentage of having a girl on next time is (in $, \%$)
