Jim's systolic blood pressure is a random variable with a mean of 145 mmHg and a standard deviation of 20 mmHg. For Jim's age group, 140 is the threshold for high blood pressure. Assume the data given follow the normal probability distribution. (Round your answer to 4 decimal places.) (a) If Jim's systolic blood pressure is taken at a randomly chosen moment, what is the probability that it will be 135 or less? (b) If Jim's systolic blood pressure is taken at a randomly chosen moment, what is the probability that it will be 175 or more? (c) If Jim's systolic blood pressure is taken at a randomly chosen moment, what is the probability that it will be between 125 and 165?
