A coin is tossed three times. An outcome is represented by a string of the sort HTT (meaning heads on the first toss, followed by two tails). The 8 outcomes are listed below. Assume that each outcome has the same probability. Complete the following. Write your answers as fractions. (If necessary, consult a list of formulas.) (a) Check the outcomes for each of the three events below. Then, enter the probability of each event. (a) Check the outcomes for each...
You have a biased coin, where the probability of flipping a heads is 70%. You flip once, and the coin comes up tails. What is the expected number of flips from that point (so counting that as flip #0) until the number of heads flipped in total equals the number of tails?
Suppose we flip a fair coin n times. We say that the sequence is balanced when there are equal number of heads and tails. For example, if we flip the coin 10 times and the results are HT HHT HT T HH, then this sequence balanced 2 times, i.e. at position 2 and position 8 (after the second and eighth flips). In terms of n, what is the expected number of times the sequence is balanced within n flips?
Suppose a coin is tossed three times eight equally likely outcomes are possible as shown below: HHH, HHT, HTH THH, TTH, THT, HTT, TTT. Let X denote the total number of tails obtained in the three tosses. Find the probability distribution of the random variable X. x P(X = x) 0 1/8 1 3/8 2 3/8 3 1/8 x P(X = x) 0 1/8 1 1/4 2 3/8 3 1/4 x P(X = x) 1 3/8 2 3/8 3 1/8...

part C (b) Consider the experiment on pp. 149-156 of the online notes tossing a coin three times). Consider the following discrete random variable: Y = 2[number of H-3[number of T). (For example, Y (HHT) = 2.2-3.1=1, while Y (TTH) = 2.1-3.2 = -4.) Repeat the analysis found on pp. 149-156. That is, (i) find the range of values of Y: (ii) find the value of Y(s) for each s ES: (iii) find the outcomes in the events A -Y...
Flipping Coins For a fair coin, the chance of getting tails is 1/2. Counting the number of tails Let's experiment with the total number of tails in n trials. Total number of tails in a small number of coin flips n Suppose we flip 10 coins (with 1 = Tails and 0 = Heads). Here are six samples of size 10. - 10 trials = 6 for (i in 1: trials) { print (sample(c(0, 1), n, replace=TRUE)) ## [1] 0...
You have a biased coin where heads come up with probability 2/3 and tails come up with probability 1/3. 2. Assume that you flip the coin until you get three heads or one tail. (a) Draw the possibility tree. (b) What is the average number of flips? Use the possibility tree, and show your calculation. 2. Assume that you flip the coin until you get three heads or one tail.
