Research has shown that the daily revenue (in thousands) of small businesses is a random variable X with median 5000, standard deviation 4000. Calculate: The probability that a business will have income greater than 4,000 The probability that a business in the next 36 days will have an average income greater than 6,000 If we take 5 businesses at random, then what is the probability that at most 2 of them have revenues greater than 4,000 If we examine these 5 businesses consecutively, then what is the probability that only the 3rd one has revenues greater than 4,000?
