Answer:
Lets assume that 1200 births are randomly selected and exactly 595 of the births are girls.
In percentage this is : [tex]\frac{595}{1200}\times100=49.58\%[/tex]
This is approx 50%. We can say that almost random 50% are girls.
So, It is unlikely because the probability of this particular outcome is very small, considering all of the other possible outcomes.
Part B: It is not unusual because 595 is about the number of girls expected.
