Firls, firls, firls
I ‘m from planet X. On planet X our children are firls and moys. The probability that our firstborn child will be a firl is 3/4 After the firstborn, the probability of the next born being the same type as the previous child is 3/5.
I have three children. They are not all moys. What is the probability that all three are firls?
There is no intentional misdirection in the question this time
