variable Consider the random experiment of flipping three fair coins. The random x :S {-1,1}, S = {HHH, HTH, THH,TTH, HHT, HTT, THT, TTT} assumes the value 1 if at least two heads were tossed and value -1 otherwise. (a) find the probability distribution p(x) of x. (b) Compute the mean and variance o of x. Show all your steps.
