The probability of getting heads from throwing a fair coin is 1/2 The fair coin is tossed 4 times. What is the probability that exactly 3 heads occur? 1/4 The fair coin is tossed 4 times. What is the probability that exactly 3 heads occur given that the first outcome was a head? 3/8 The fair coin is tossed 4 times. What is the probability that exactly 3 heads occur given that the first outcome was a tail? 1/8 The...
3. Consider a coin-die experiment: One flips a fair coin at first. If he gets a head, then he will roll a 6-sided fair die; otherwise, he will roll a 6-sided unfair die, which has probability to get i faces up (i = i, . . . , 6). If one gets a 2 faces up, what is the probability that he got a tail when he flipped the coin? 2.1
[Geometric] Find the probability that a person flipping a fair coin gets: 1. the first head on the 4th toss 2.the first head on the 3rd toss
Problem 10) A fair coin is tossed 20 times. A fair coin means that the probability of getting a head is the same as the probability of getting a tril. Let X be the number of coins of getting head. Note that there are only two possible outcomes: getting head or tail after tossing the coin X follows a binomial distribution with n =20, p=0.5. Answer the following questions (Question) Find PX-17).
Draw a probability tree diagram for the following experiment: a fair coin is tossed; if a head appears uppermost, then the fair coin is tossed again, otherwise an unfair coin with P (Head) = 0.55 is tossed. What is the sample space of this experiment? What is the associated probability distribution in this experiment? :explain the probability distribution part
Game of dice - fair dice: If I throw a number >= 5 I win. If he throws a number =< 4 he wins. I throw the first dice. Given that he loses(throws a number >4) what is the probability of me winning ? What is the expected number of throws before either of us wins?
Consider an experiment such that we flip a coin until the first time a heads is observed. Let E be the event that the first time a heads turns up is on an odd numbered flip (so we get a heads on our 1st, 3rd, or 5th flip and so forth). What is the probability that E occurs?

Consider the sample space of outcomes of two throws of a fair die. Let Z = be the minimum of the two numbers that come up. List all the values of Z. Compute its probability distribution. Consider the sample space of outcomes of two tosses of a fair coin. On that space define the following random variables: X = the number of heads; Y = the number of tails on the first toss. For...
A fair coin is tossed 10 times. What is the probability that the coin lands head at least 8 times? a) 0.0527 b) 0.0547 c) 0.1094 d) 0.0440 e) 0.0537
QUESTION 8 Problem 8) A fair coin is tossed 20 times. A fair coin means that the probability of getting a head is the same as the probability of getting a tail. Let X be the number of coins of getting head. Note that there are only two possible outcomes: getting head or tail after tossing the coin. X follows a binomial distribution with n=20, p=0.5. Answer the following questions. (Question) Find the expected value of X, E(X). QUESTION 9...
