    Imagine that you have a coin and you are flipping it 10 times. After the 5th toss the coin has come up heads 5 times in a row. What is the probability that the coin will come up heads, again, on the 6th toss?

    Suppose there are 10 coins laid out in front of you. All of the coins are fair (i.e. have an equal chance of heads or tails) except one, which flips to heads every time. You draw one coin at random and flip it 5 times. If each of the 5 flips results in

    Carolyn tested a coin to see if it was evenly weighted. She flipped the coin 100 times and came up with 42 heads and 58 tails. How does the relative frequency of tails to heads compare to the probability of tails in this experiment? A. The relative

    A student claims that if a fair coin is tossed and comes up heads 5 times in a row, then, according to the law of averages, the probability of tails on the next toss is greater than the probability of heads. What is your reply?

    We have k coins. The probability of Heads is the same for each coin and is the realized value q of a random variable Q that is uniformly distributed on [0,1]. We assume that conditioned on Q=q, all coin tosses are independent. Let Ti be the number of

    A six sided number cube is rolled and a coin is flipped. What is e probability that the number on the cube is less than 4 and the coin lands on heads? I think the answer might be 1/3. Heads and tails is 1 and less than 4 is 3. I am not sure.
