Question

Joe says “ No our second baby can’t be albino because only one out of every four of our children should be albino. We already have one albino child, so our next three children should not be albino.” Is Joe right? Explain why or why not.

Answer 1

No, probability is independent. Just because they had one albino child does not prevent them from having another albino child. Every time they have a child, there will always be a 1/4 chance that child will be albino, regardless of the previous children.
