- How do you calculate the probability of different gender outcomes? You calculate the probability by determining the total number of outcomes and the favorable outcomes; for two children, it's 2 favorable outcomes (boy-girl) out of 4 total combinations.
- Is the probability of having a boy or girl the same for each child? Yes, each child has an independent 50% chance of being a boy or a girl.
