The number of gallons of paint that Home Depot sells in a given day

The number of gallons of paint that Home Depot sells in a given day is normally distributed with a mean of 160 gallons and a standard deviation of 55 gallons (I realize that the distribution is probably different for weekends compared to weekdays, but just assume everyday has the distribution). What is the probability that on a randomly chosen day, Home Depot sells more than 120 gallons of paint? (please round your answer to 4 decimal places)
