Question 3 (Based Coin, 20 points). A trick coin comes up heads only 1/3 of the time, a You flip the coin until it comes up hoads. What is the distribution of the number of flips required! What is the probability that it takes erectly flips until you get the first heada? 15 pinta You ftip the coin 6 times and count the number of head. What distribution gives the total county What is the probability that you get exactly Shrads/5 points) Suppose you flip the coin 20 times. Using the normal model, what is the approximate probability that at least half of the flips come up headsy 15 points) d How many times would you have to flip the coin so that the probability of it coming up heads at least half the time is less than 2.5%9/5 points/
