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?

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.

You suspect that a coin is biased such that the probability heads is flipped (instead of tails) is 52%. You flip the coin 51 times and observe that 31 of the coin flips are heads. The random variable you are investigating is defined as X = 1 for heads and X = 0 for tails, and you wish to perform a "Z-score" test to test the null hypothesis that H0: u = 0.52 vs. the alternative hypothesis Ha: u > 0.52....
(1 point) Consider a game played by flipping biased coins where the probability of heads is 0.14. You first choose the number of coins you want to flip You must pay $1.5 for each coin you choose to flip. You flip all the coins at the same time. You win $1000 if one or more coins comes up heads How many coins should you flip to maximize your expected profit? Answer: What is your maximum expected profit? Answer: $ (Your...
Assume that a coin is flipped where the probability of coin lands "Heads" is 0.49. The coin is flipped once more. This time, the probability of obtaining the first flip's result is 0.38. The random variable X is defined as the total number of heads observed in two flips. On the other hand, the random variable Y is defined as the absolute difference between the total number of heads and the total number of tails observed in two flips. Calculate...
Simulate the flipping of a coin Print the result of the coin flip : use off numbers for Heads . and even numbers for Tails Update the number of times the result is Heads Update the number of times the coin has been flipped struct coin_prob{ int heads; int flips; }; void coin_flip(struct coin_prob * coin); You may use a rand functioon (assume its already been seeded), but no other pre-defined function
But change it to be a biased coin where Pr(flipping tails) = 0.25 and Pr(flipping heads) = 0.75
Suppose you flip a fair coin repeatedly until you see a Heads followed by another Heads or a Tails followed by another Tails (i.e. until you see the pattern HH or TT). (a)What is the expected number of flips you need to make? (b)Suppose you repeat the above with a weighted coin that has probability of landing Heads equal to p.Show that the expected number of flips you need is 2+p(1−p)/1−p(1−p)
A coin is biased such that the probability of flipping heads is .2. If the coin is tossed 15 times, what is the probability of getting exactly 5 heads?
The Belgian Euro coin is known to be biased: it has a probability of 0.56 of landing on heads when flipped, and a probability of 0.44 of landing on tails. Answer the questions below using the event ‘landing on heads’ as a success, and ‘landing on tails’ as a failure. 1. What is the expected value for heads of flipping the Belgian Euro coin 50 times? 2. What is the standard deviation for flipping the Belgian Euro coin 50 times?
Answer part a and part b please!!! (a) What is the conditional probability that exactly four Tails appear w when a fair coin is flipped six times, given that the first flip came up Heads? (I.e. the coin , then is flipped five more times with Tails appearing exactly lour times.) (b) What if the coin is biased so that the probability of landing Heads is 1/3? (Hint: The binomial distribution might be helpful here.) (a) What is the conditional...
