Question 1 Report

The first four children of a couple were all girls. The probability that the fifth will also be a girl is
Answer Details
The probability of having a girl or a boy is always the same in each birth and is 1/2 or 50-50. Therefore, the probability of having a girl in the fifth birth is also 1/2 or 50-50, regardless of the gender of the previous children. This is because the gender of the previous children does not affect the gender of the next child since each birth is an independent event. So, the answer is 1/2 or 50-50.
