Answer:
The probability of all three children being girls is 0.125.
Step-by-step explanation:
The events of a boy being born and the girl being born is equally likely.
That is, P (G) = P(B) = 0.50.
The gender of <em>n</em>th baby born is independent of the gender of the (<em>n</em> - 1)th baby born.
Compute the probability of all girls as follows:
P (All three girls) = P (G) × P (G) × P (G)
Thus, the probability of all three children being girls is 0.125.
