Monitor three customers purchasing smartphones sat the Phonesmart store and observe whether each buys an Apricot phone for $450 or a Banana phone for $300. The random variable N is the number of customers purchasing an Apricot phone. Assume N has the PMF below. Find the ecpected value E(N) by using the following: a) The theorem: Given a rondom variable X with PMF PX(x) and the derived random variable Y = g(X), the expected value of Y is E[Y] = μY = Σ[ g(x)*PX(x) ] b) The definition: The expected value of X is E[X] = μX = Σ[ x*PX(x) ]

An ordinary (fair) coin is tossed 3 times. Outcomes are thus triples of "heads" (h) and "tails" (t) which we write hth, ttt, etc. For each outcome, let N be the random variable counting the number of tails in each outcome. For example, if the outcome is hht, then = Nhht1. Suppose that the random variable X is defined in terms of N as follows: =X−2N2−4N3. The values of X are given in the table below. Outcome ttt hhh htt hht thh tht hth tth Value of X 3 −3 −3 −5 −5 −3 −5 −3 Calculate the probabilities P (X = x) of the probability distribution of X. First, fill in the first row with the values of X. Then fill in the appropriate probabilities in the second row. Value x of X P (X = x)
