The distribution of SAT scores of all college-bound seniors taking the SAT in 2014 was approximately normal with a mean of 14971497 1497 1497 and standard deviation of 322 322 322 322 . Let X=X= X= X, equals the score of a randomly selected tester from this group. Find P(X<1200)P(X<1200) P(X<1200) P, (, X, is less than, 1200, ).
