    A fair coin is flipped independently until the first Heads is observed. Let the random variable K be the number of tosses until the first Heads is observed plus 1. For example, if we see TTTHTH, then K = 5. For k 1, 2, , K, let Xk be a continuous random variable that is uniform over the interval [0, 5]. The Xk are independent of one another and of the coin flips. LetX = Σ i Xo Find the...

    We have four fair coins, each of which has probability 1/2 of having a heads outcome and a tails outcome. The experiment is to ip all four coins and observe the sequence of heads and tails. For example, outcome HTHH means coin 1 was heads, coin 2 was tails, coin 3 was heads, coin 4 was heads Note that there are 16 total outcomes, and we assume that each one is equally likely. What is the probability that at there...
