Expert Answer

Step 1

From the given information,

Total number of births = 912

Total number of baby girls out of total births = 462

 Total number of baby boys = 450

As given that boys and girls are equally likely.

Thus,

P(baby girl) P(baby boy)
1
2

P(baby girl) P(baby boy) 1 2

Step 2

Hence, the required probability can be computed as:

By using binomial formula:

f(Xx)(1-p)*^
,x=0,1,2
462
92462
912
P(X 462)
462
=0.02441
