The coin has 95 percent confidence interval on the probability that it will come up head.
So to test it's fairness we can practically flip a coin 10 to15 times or 20 times and find out the probability of occurrence of head and calculate it's percentage of occurrence of head.Then we can check it's fairness,if it's more than 50 percent then it's biased or unfair coin.
For the above coin, it's given the probability of head is 95 percent,so if I toss the coin for 10 times,then at least 9 times head will occur and almost 10 times head will occur.
Hence we checked and verified the unfairness of the coin by the above method.

Hello! Can you help me understand how to approach to solve the following problem (viewing this as a Markov Chain problem)? In a sequence of independent flips of a fair coin that comes up heads with probability .6, what is the probability that there is a run of three consecutive heads within the first 10 flips?

Question 2 Suppose you have a fair coin (a coin is considered fair if there is an equal probability of being heads or tails after a flip). In other words, each coin flip i follows an independent Bernoulli distribution X Ber(1/2). Define the random variable X, as: i if coin flip i results in heads 10 if coin flip i results in tails a. Suppose you flip the coin n = 10 times. Define the number of heads you observe...
