3. [-/4 Points] DETAILS PODSTAT6 7.E.053.MI.S. MY NOTES ASK YOUI A company surveyed 2,600 North American airline passengers and reported that approximately 65% said that they carry a smartphone when they travel. Suppose that the percentage is 65%. Consider randomly selecting six passengers and define the random variable x to be the number of the six selected passengers who travel with a smart probability distribution of x is the binomial distribution with n = 6 and p = 0.65. (Use SALT. Round your answers to four decimal places.) LA USE SALT (a) Calculate p(4). Interpret this probability. O the probability that a random sample of 6 passengers will contain at least 4 passengers who travel with a smartphone O the probability that a random sample of 6 passengers will contain more than 4 passengers who travel with a smartphone O the probability that a random sample of 6 passengers will contain exactly 4 passengers who travel with a smartphone O the probability that a random sample of 6 passengers will contain less than 4 passengers who travel with a smartphone O the probability that a random sample of 6 passengers will contain at most 4 passengers who travel with a smartphone (b) Calculate p(6), the probability that all six selected passengers travel with a smartphone. (c) Calculate P(x 2 4).Twenty percent of the customers of a grocery store use express checkout. Consider five randomly selected customers, and let x denote the number among the five who us checkout. (Round your answer to three decimal places.) LO USE SALT (a) Calculate p(2), that is, P(x = 2). P(2) = (b) Calculate P(x s 1). P(x
