An engineering firm offers testing for electrical products. Currently they are testing a type of compact portable music player. They randomly select a number of the music player and conduct a series of tests and compute an overall score for each unit based upon the results of the testing routine. They determine that the test scores are normally distributed with a mean of 374 and a variance of 1,090. A unit is deemed faulty if it scores below 320. Find the probability of a random unit being faulty. Give your answer as a decimal to 2 decimal places.
