It seems that quite irrelevant information was introduced, yet the probability of the sex of the other child has changed dramatically from what it was before (the chance the other child was a girl was 2/3, when it was not known that the boy was born on Tuesday).
Чини се да смо увели сасвим небитне информације, али вероватноћа пола другог детета се драматично променила од онога што је било пре (шансу да је друго дете била девојчица је 2/3, кад нисмо знали да је дечак рођен је у уторак).
