In 2025, а study wаs cоnducted thаt fоund the weekly grоcery bill for a family of 4 in the U.S. had a mean of $225. Assume this data is normally distributed and that the true standard deviation is known to be $58.    Find the probability as a decimal that a randomly selected weekly grocery bill for a family of 4 in the U.S. is either less than $275 or more than $180.  (Type your answer as a decimal rounded to 3 decimal places. So if you thought the answer was 0.12345 then you would type in 0.123)
