My husband and I just had our eighth child another girl. what’s the probability of the next child to be a boy?

Question

We need to talk Ben,  said Melissa I know we have eight children, but i want a boy! My dad is a math teacher and he said that the chances of having 9 boys in a row is 1 out of 512. Right , and the doctor said said 1 out of 100 last time,too.

Answer 1

Assuming there's no physical reason for all females, so the probability is random 1:1, the probability of a boy next time is still 50% (that's the mathematical answer). However, it seems more likely that there is a medical, biological, or genetic reason for all female offspring. Only a geneticist would be able to determine that!
