What is the probability that their next child will be a girl?

Question: A couple has five sons. They would like to have a daughter, and they have decided to try again.

There are a total of 64 possible birth orders, so that P is equal to 1/2 for each order. This is called a binomial distribution, and is what we will use to answer this question.

What is the probability that their next child will have type O blood?

A man with AB blood marries a woman with O blood. What is the probability that their next child will also have AB blood?

What is the probability that their next baby will be blue-eyed?

Albinism is a recessive trait.

What is the probability that their future child will have dimples and freckles?

The sex of a child is determined by the chromosomes that the father produces.

As the mother only has X chromosomes, she cannot produce Y chromosomes. If she did, she could produce a male child.

There are a total of 32 sequences that have five children, so each time there is a chance for a male or female child.

Hence, we have a 50% probability that one of the children will be a female.

The probability that the first child will be a boy is 0.5, and the probability that the second child will be a girl is 0.5. The probability that the third child will be a boy is 0.1562, and so on.
