The Chapin Social Insight Test evaluates how accurately the subject appraises other people.In the reference population used to develop the test, scores are approximately normally distributed with mean 25 and population standard deviation five.The range of possible scores is between 0 to 41.What is the probability of a score of 33 or less?

(Please write your answer as a decimal. The testing system is not able to recognize a % sign. So if you have 1.23% then this should be written as .0123 which is the decimal equivalent.)
