3- (20 points) A random experiment consists of simultaneously and independently flipping a coin five times and observing the n-5 resulting values facing up. The coin is biased with: P(heads) - 0.75 : P(tails) p-0.25 Define a Random Variable (RV) X equal to the number of fails that we observe during the flips. a) Give the probability P. that the random variable X will take on the value 3 ANSWER: P,= (simplified number) b) Give the mean of X, that...

Consider a pay-to-play game which involves flipping a coin three (3) times. The payout for the game depends on the number of heads obtained in the three coin flips. Let the discrete random variable X represent the number of heads. a) What is the probability P{X = k} associated with each value k of the random variable? b) Suppose that the game has a payout of X^2 dollars. What is the minimum amount that should be charged for admittance (player...
