Answer:
49.97% probability they have one boy and one girl.
Step-by-step explanation:
For each children, we have these following probabilities
0.513 = 51.3% probability of being a boy
1-0.513 = 0.487 = 48.7% probability of being a girl
If a family has two children (not twins), what is the probability they have one boy and one girl?
It can be either a boy and then a girl, or a girl than a boy.
So
[tex]P = 2*0.513*0.487 = 0.4997[/tex]
49.97% probability they have one boy and one girl.
