If there are 1500 individuals who participated in the study, approximately ______ individuals have a systolic blood pressure of at most 120. 2. About ______% of the individuals aged 30 to 40 has a systolic blood pressure between 112 to 128. 3. The probability that the systolic blood pressure of the individuals aged 30 to 40 is no less than 140 is ______.
