Question

What are the odds of a person having a boy for their fourth child if the previous three children were all girls?

Answer 1

The odds is the ratio of the probability of an event occurring to that of its not occurring. P(boy) = 0.5. P(girl) = 0.5.
Therefore the odds of having a boy are 1:1.

Answer 2

i honestly would of have said its a  50/ 50 chance but I think it all depends on the gene.... hope this helps
