For Number 1-3: Medical researchers have determined so-called normal intervals for a person’s blood pressure, cholesterol, triglycerides, and the like. In a given study, it was found that the systolic blood pressure of individuals aged 30 to 40 follows the normal distribution with a mean of 120 and a standard deviation of 8. 1. 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 ______.
