Here is another math (probability) problem that I have discovered, that I enjoyed solving - and challenged Carlos to solve.
I'll leave the answer up to you.
Part I: Mr. Jones has two children. The older child is a girl. What is the probability that both children are girls?
Part II: Mr. Smith has two children. At least one of them is a boy. What is the probability that both children are boys?
If you want the answer, post a comment. I'll reply. Or go here.
