If you’re pregnant, theprobability of having a boy or girlis the same: 50%. However, if you already have one child (say, a boy), your odds change. Given that your first child is a boy, your odds of having another boy drop to one third (33.33%). The reason for th...

Assume that each child born is equally likely to be a boy or a girl. If a family has two children, what is the conditional probability that both are girls given that i. the youngest is a girl, ii. at least one is a girl? View Solution It is given that a family of 2 children ha...
In Example 23.2.1 the overall probability of a particular value of a discrete random variable was computed as a product in which one factor was the number of equally likely ways in which that value could be obtained, and the other factor was the probability of each mutually exclusive occurrenc...
Probability is not just "Do you have better odds if you go for this girl or that?" but also "What are the odds you'll run into the girl you're after in this, that, or the other locale?" When you understand probability -- and more specifically, the probability of meeting a particul...
H1H1: The baby is a brown-haired boy. H2H2: The baby is a blond-haired girl. H3H3: The baby is a dog. Then, consider two scenarios: We're presented with evidence in the form of a picture of a blond-haired baby girl. We find this evidence supports H2H2 and opposes H1H1 and...
