A particular coin is biased. Each timr it is flipped, the probability of a head is P(H)=0.55 and the probability of a tail is P(T)=0.45. Each flip os independent of the other flips. The coin is flipped twice. Let X be the total number of times the coin shows a head out of two flips. So the possible values of X are x=0,1, or 2. a. Compute P(X=0), P(X=1), P(X=2). b. What is the probability that X>=1? c. Compute the...

hello Coin 1 is biased, with P(H)=0.2; Coin 2 is also biased, with P(H)=0.6; Coin 3 is fair. One of these coins is randomly selected, and then flipped. Calculate: a) P(result of the flip is T). b) P(coin selected was the fair one, if the result of the flip is H). c) Assuming now that one of the coins is randomly selected and then flipped 2 times, calculate P(coin selected was the fair one, if result of the flips is...

Let X be the number of times I flip a head on a fair coin in 1 minute. From this description, we know that the random variable X follows a Poisson distribution. The probability function of a Poisson distribution is P[X = x] = e-λ λx / x! 1. What is the sample space of X? Explain how you got that answer. 2. Prove that the expected value of X is λ. 3. Given that λ = 30, what is...
