On a graphing calculator, you can use the function normalcdf(lower bound, upper bound, μ, σ) on the distr menu to find the area under a normal curve for values of x between a specified lower bound and a specified upper bound. you can use −1e99 as the lower bound to represent negative infinity and 1e99 as the upper bound to represent positive infinity. suppose that cans of lemonade mix have amounts of lemonade mix that are normally distributed with a mean of 350 grams and a standard deviation of 7 grams. what is the probability that a randomly chosen can has less than 336 grams or more than 371 grams of lemonade mix? give the probability to the nearest ten-thousandth. the probability is__
