Question

A couple with eight daughters decides to have one more baby, because they think
this time they are sure to have boy! Is this reasoning accurate?

Answer 1

nope - same old 50-50 chance.

Although, given their previous children, I ct the chances are high that they'll have another daughter. There may be something other than random chance at work here.
