Vedclass · Answer

(A) In humans,sex determination is based on the $XY$ chromosome system. During fertilization,the male gamete (sperm) carries either an $X$ or a $Y$ chromosome,while the female gamete (ovum) always carries an $X$ chromosome.Each pregnancy is an independent event. The probability of having a boy or a girl remains $50\%$ for every conception,regardless of the gender of the previous children.Therefore,the probability of the $6^{th}$ child being a son is $1/2$ or $50\%$.

$A$ family has five girls and no son. What is the probability of having a son as the $6^{th}$ child (in $\%$)?
