Children Probablity


John and Jenni are a married couple. They have two kids, one of them is a girl. Assume safely that the probability of each gender is 1/2.
What is the probability that the other kid is also a girl?

Hint: It is not 1/2 as you would first think.

    Probabilities of individual events are independent of each other and the outcome of the first  (or subsequent) events. Hence, the probability of the second child to be a girl will be 1/2 x 1/2 = 1/4
