Step-by-step explanation:
Binomial probability formula :-
We assume that male and female births are equally likely and that the birth of any child does not affect the probability of the gender of any other children.
The probability of of getting a boy = The probability of getting a girl = 0.5
Now, the probability of exactly nine boys in ten births will be :-
Hence, the probability of exactly nine boys in ten births = 0.009765625
