Answer: 0.25
Step-by-step explanation:
Given: The total number of outcomes ( boy-boy, girl-girl, girl-boy, and boy-girl.)= 4
The number of favorable outcome (boy-girl)=1
Now, the probability that she will have boy-girl is given by :-
[tex]\text{P(boy-girl)}=\frac{\text{favorable outcome}}{\text{total outcomes}}\\\\\Rightarrow\ \text{P(boy-girl)}=\frac{1}{4}=0.25[/tex]
Hence, the probability that she will have boy-girl is 0.25.
