Let Z be the number of the flipping when first Head appears, and M be the number of flipping when second head appears. We know the probability of getting a head is p and probability of getting a tail is then 1-p.

The questions are: a) Find the probability distribution of Z and M. b) Are Z and M independent? Give the reason

1) Let S = {H, T} be the sample space associated to the fair coin-flipping. Is {H} independent from {T}? 2) Let S = {HH, HT, TH, T T} be the sample space associated to flipping fair coin twice. Consider two events A = {HH, HT} and B = {HT, T H}. Are they independent? 3) Suppose now we have a biased coin that will give us head with probability 2/3 and tail with probability 1/3. Let S = {HH,...

A coin with P[Heads]= p and P[Tails]= 1p is tossed repeatedly (the tosses are independent). Define (X = number of the toss on which the first H appears, Y = number of the toss on which the second H appears. Clearly 1X<Y. (i) Are X and Y independent? Why or why not?

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...
