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?
Since a coin is weighted, tails is more likey. When you test the coin by flipping it 10 times, you observe that tails comes up 9 times. How likely is it that such extreme behavior would occur in a fair coin?(In other words, assuming that the coin is fair, what is the probability of getting tails 9 or 10 times?)
1. Consider flipping a fair coin three times and observe whether it lands heads up or tails up. Let X the number of switches from either head to tail or vice versa. For example, when THT is observed, the number of switches is 2 and when HHH is observed, the number of switches is 0. Also, let Y be the number of tails shown in the three times of fipping. (a) List all the values of the joint probability mass...
Suppose that a legal coin has a 50% probability of flipping "heads" (Pheads = 0.5) and a 50% probability of flipping "tails" (Ptails = 0.5). If this legal coin is flipped nine times, what is the probability of flipping five heads and four tails in any order? Group of answer choices None of the answers provided here. 3.9% 9.2% 55.6% 12.6% 6.8% 24.6% 31.6%
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...
When considering data obtained from flipping one coin four times and obtaining all tails, what will the maximum likelihood approach calculate? (Consider that there are three models possible for this coin toss: 1. A fair coin model. 2. A coin with both sides heads. And 3. A coin with both sides tails. Priors are 1. 99.8%, 2. 0.1%, 3. 0.1%) A. The probability of obtaining all tails, averaged over all possible models (i.e. ((.5)^4 * 0.998) + (0 * 0.001)...
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?
But change it to be a biased coin where Pr(flipping tails) = 0.25 and Pr(flipping heads) = 0.75
In flipping a coin 12 times and observing heads or tails, how many different outcomes can be obtained?
You toss a penny and observe whether it lands heads up or tails up. Suppose the penny is fair, i.e., the probability of heads is 1/2 and the probability of tails is y. This means every occurrence of a head must be balanced by a tail in one of the next two or three tosses. if I flip the coin many, many times, the proportion of heads will be approximately %, and this proportion will tend to get closer and...
