Suppose the movie theatre box office of a new film to be released is predicted to follow a Normal distribution, with mean equals 100 million dollars and standard deviation equals 20 million dollars. What is the probability that the box office will be at least 70 million? What is the probability that the box office will be either more than 70 million or less than 40 million dollars? There is 80% probability that the box office will be greater than or equal to million. (NOTE: Round your answers to 2 decimal places. Do not type in any non-integer symbol or text other than decimal.)
