  1. If you flip a coin once and denote the result using y variable, let y=1 if you get a head, and y=0 if you get a tail, further suppose the probability to get a head is β, what is the probability function of the random variable y?
A.

Pr(y)=β1-y(1-β)y
B.

Pr(y)=βy(1-β)1-y
C.

Pr(y)=yβ(1-y)(1-β)
D.

Pr(y)=y(1-β)(1-y)β

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...

You are going to successively flip a coin until the pattern HHT appears; that is until you observe two successive heads followed by a tail. In order to calculate some properties of this game, you set up a Markov Chain with the following states: 0, H, HH, HHT, where 0 represents the starting point, H represents a single observed head on the last flip, HH represents two successive heads on the last two flips, and HHT is the sequence you...

There are X, Y and Z coins in a box. X is a fair coin; Y is a coin with tail on both sides and Z is a coin with a probability of 2/5 of the head. Let's imagine we pulled a random coin out of the box. Since it is known that it is tail, what is the probability that this money will be X? A. 1/3 B. 7/10 C. 5/21 D. 3/5
