5. If you toss a coin 10 times, you got 8 head out of ten tosses. What is the probability of this event if the coin is fair (P[X=8|Coin=normal], X is a random variable representing number of head out of ten tosses)? What is the probability of this event if the coin is fake( P[X=8|Coin=fake])?

3. Sum rule for conditional probability Let’s assume there is 1 fake coin out of 1000 coins. ( P[Coin=fake] = 0.001 ) The probability of showing head for fake coin is 0.9 (P[Head | Coin=fake] = 0.9). For normal coin, the probability of showing head is 0.5 (P[Head | Coin=normal] = 0.5). If you have a coin and toss it, what is the probability that you will get a head and the coin is fake (P[Head & Coin=fake])? What 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...
