Conditional probability · Family
At least one boy
A family has 2 children, each independently a boy or a girl with equal probability. You learn that at least one of them is a boy. What is the probability that all 2 are boys?
Answer with a probability. First lock in a gut guess with an 80% range, then solve it properly, then watch a simulation settle on the truth.
