2) (Difficult problem: i don't expect that people can solve it) Let X be a exponential variable with parameter λ 2, Now, we have a unbiased coin. We throw it. If we get tall, we take the number X. If we get head we take 3 times X. The result is called Z. What is the probability density of Z. (Read up about the probability density of exponential variable online). So, in other words, we generate a random number X...

Imagine an experiment where we flip a coin 6 times, and get “head, tail, head, head, head, head”. Which of the following statements are true? a) The coin is not fair b) The coin’s tail probability is 1/6 c) The sequence "head, tail, head, head, head, head" is an outcome in the sample space. d) The sample space of the experiment is {head, tail}

A coin will be tossed multiple times. Probability of head is 1/2, and probability of tail is 1/2. they are independent from each other. X is a random variable that counts how often the coin must be tossed until the first head appears. calculate for all k=1,2,3,..., how big the probability is for: i) X=k ii) X>k iii) X<k
You have a biased coin where heads come up with probability 2/3 and tails come up with probability 1/3. 2. Assume that you flip the coin until you get three heads or one tail. (a) Draw the possibilit...

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...

We play a game where we throw a coin at most 4 times. If we get 2 heads at any point, then we win the game. If we do not get 2 heads after 4 tosses, then we loose the game. For example, HT H, is a winning case, while T HT T is a losing one. We define an indicator random variable X as the win from this game. (d) (5 Pts.) On average how many times do you...

Probability Puzzle 3: Flipping Coins
If you flip a coin 3 times, the probability of getting any sequence is identical (1/8). There are 8 possible sequences: HHH, HHT, HTH, HTT, THH, THT, TTH, TTT Let's make this situation a little more interesting. Suppose two players are playing each other. Each player choses a sequence, and then they start flipping a coin until they get one of the two sequences. We have a long sequence that looks something like this: HHTTHTTHTHTTHHTHT.......
