The example used to introduce conditional probability described a family with two children each of whom was equally likely to be a boy or a girl. The example showed that if it is know n that one child is. a boy, the probabiliiy that the other child is a boy is 1/3. Now imagine ihe same kind of family—two children each of whom is equally likely to be a boy or a girt. Suppose you meet one ot the children and that child is a boy. What is the probability that the other child is a boy? Explain. (Be careful. The answer may surprise you.)
To find out the probability that the other child is a boy.
It is given that if it is known that one child is boy, the probability that other child is a boy is .
Given a family- two children each of whom is equally likely to be a boy or a girl.
According to the given example of conditional probability there can be following outcomes
