What is more likely to happen?


Parents buy cookies for their kids. They are saving money so they buy two discounted ones (few days after best before). They don’t want to look greedy so they also buy two cookies for the full price.

When they come home their two kids grab cookies, and each get two. They don’t check best before so their choice is random.

Do you think that life is fair and each kid gets one expired and one good cookie? Or one kid gets both expired? What is more likely to happen?

    There are 6 options to distribute 4 cookies between 2 kids (4 above 2):

    • One kid and two expired cookies, there are 2 possibilities: kid 1 has 2 good ones or the 2 expired ones.
    • If each kid is to get one good and one expired there are 4 possibilities: each can get one of two expired and one of two good – (2×2).

    In real life though the less likely possibility is sometimes more likely to happen :o)
