You select a coin at random: 2/3 of the coins are unfair, 1/3 of the coins are fair. The fair coins are equally likely to flip heads or tails. The unfair coins flip heads 3/4 of the times, and tails 1/4 of the times. You flip the selected coin and get heads or tails. Find (1) the probability that the selected coin is fair given the flip is heads, (2) the probability that the selected coin is fair given the...

Deriving fair coin flips from biased coins: From coins with uneven heads/tails probabilities construct an experiment for which there are two disjoint events, with equal probabilities, that we call "heads" and "tails". a. given c1 and c2, where c1 lands heads up with probability 2/3 and c2 lands heads up with probability 1/4, construct a "fair coin flip" experiment. b. given one coin with unknown probability p of landing heads up, where 0 < p < 1, construct a "fair...

A jar contains infinitely many coins which come up Tails with proba- bility p. A person selects a coin from the jar and flips it on a table. In the following way, they continue flipping coins until all coins on the table show Tails: If the last flip came up Heads, they select a coin from the jar and flip it on the table. On the other hand, if the last flip came up Tails, they select a coin from...

If we flip three coins at the same time, the population of the number of resulting heads has a mean of 1.5 and a standard deviation of .71. Assume that many samples of size n are taken from a large population of sets of coin flips and that the mean number of heads is computed for each sample. a) Find the mean and standard deviation (to 4 decimal places) of the resulting distribution of sample means for n = 36....

A student wants to determine if pennies are really fair, meaning equally likely to land heads up or tails up. He flips a random sample of 50 pennies and finds that 28 of them land heads up. Calculate the p-value and state the conclusion. Use ? = .05. (NO EXCEL)

Three coins are in a barrel with respective probabilites of heads 0.3, 0.5, and 0.7. One coin is randomly chosen and flipped 10 times. Let N = # of heads obtained in the ten flips. a. Find P(N = 0). b. Find P(N=n), n = 0, 1, 2, ..., 10. c. Does N have a binomial distribution? Explain. d. If you win $1 for each heads that appears, and lose $1 for each tails, is this a fair game? Explain.

An unfair coin is made so that heads is seven times as likely to come up as tails when the coin is flipped. An experiment consists of flipping this coin just once What weight (or probability) does the outcome 'heads' have? What weight (or probability) does the outcome 'tails' have? Enter your answers as whole numbers or fractions in lowest terms. An experiment has sample space S={a,b,c,d,e}. Outcomes b,c,d,e are equally likely while the likelihood of outcome a is Wa=7/19...
