Assume that a randomly selected subject is given a bone density test. Those test scores are normally distributed with a mean of 0 and a standard deviation of 1. Find the probability that a given score is less than - 1.33 and draw a sketch of the region. Sketch the region. Choose the correct graph below. OA. OB. OC. OD. -1.33 1.33 1.33 -1.33 -1.33 The probability is (Round to four decimal places as needed.)
