1. There is this coin that is not balanced. The probability of getting a head is four times the probability of getting a tail. Suppose this coin is tossed 5 times. Give the probability of getting at least 1 head. Express your answer as a decimal to several places past the decimal or as a common fraction. Show work.

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...
