Answer 2

Answer: 0.25

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 :-

`\text{P(boy-girl)}=\frac{\text{favorable outcome}}{\text{total outcomes}}\\\\\Rightarrow\ \text{P(boy-girl)}=(1)/(4)=0.25`

Hence, the probability that she will have boy-girl is 0.25.
