Question

A family has 4 horses bred from the same set of parents. All of their horses are mares (females). They are planning on having one more horse to complete their herd. A neighbor comments that they are much more likely to end up with a male horse the next time around. Is the neighbor’s reasoning correct?

a. Yes, they are more likely to end up with a male horse in order for the probabilities of male and female to get back to 0.5
b. No, the probability of the new horse being male or female remains 0.5, regardless of what its older siblings are.
c. Yes, after having so many female horses in a row, the breeding pair is due to have a male.
d. No, these horses must be genetically prone to having female offspring
