Скачать или смотреть Two Conditional Probability Examples (what's the difference???)

We investigate two basic conditional probability examples that are ALMOST identical but slightly different. We look at the probability of two children both being girls given either that we are told one of the two kids is a girl, or that we are told the oldest of the two kids is a girl.

Conditional Probability Formula: P(A|B) = P(A and B)/P(B)
