    It would be (1/2)^5 because the probability of getting tails is 1/2 and you're flipping 5 coins

    you should stem it into 5 events with the different possibilities and then see how many of the branches lead up to having 5 ts in a row.

    it should be 1/32 possibilities.

    because there are 32 ways you can have t and h put together 5 times.

    Ah, I see. Well, I like the simplicity of your answer. I'm taking stats, and oh my gosh. You have to come up with all of these reasons for why you have your answer! haha
