A company surveyed 2,600 North American airline passengers and reported that approximately 70% said that they carry a smartphone when they travel. Suppose that the actual percentage is 70%. Consider randomly selecting ten passengers and define the random variable x to be the number of the ten selected passengers who travel with a smartphone. The probability distribution of x is the binomial distribution with n = 10 and p = 0.7. (Round your answers to three decimal places.)     (a) Calculate p(8). p(8) = (b) Calculate P(x ≤ 6). P(x ≤ 6) = (c) Calculate the probability th
