Answer:
Option A. 0.25
Step-by-step explanation:
Ellen plans two children but does not know if they will be boy-boy, girl-girl or boy-girl.
For the first baby to be the girl child
Probability = [tex]\frac{1}{2}[/tex]
Similarly probability for second baby to be the girl child will be [tex]\frac{1}{2}[/tex]
Now both the children are girl to probability for this event will be
= [tex]\frac{1}{2}[/tex] × [tex]\frac{1}{2}[/tex]
= [tex]\frac{1}{4}[/tex]
= 0.25
Option A. 0.25 is the answer.
