Hi folks!
I have the following exercise to solve:
Let's imagine a new family with three children. Assuming that each child is equally likely to be a boy or a girl, and that the gender of each subsequent child is independent of the gender of its older siblings.
Thanks in advance!

- What is the probability of three girls?
- What is the probability of two girls and one boy?
- What is the probability of one girl and two boys?
- What is the probability of three boys?
- What is the probability that all children are girls given that the oldest child is a girl?
- What is the probability that all children are girls given that one of the children is a girl?
Thanks in advance!
