Based on data from the National Health Survey, women between the ages of 24 and 36 have an average systolic blood pressures (in mm Hg) of 125.5 with a standard deviation of 22.3. Systolic blood pressure for women between the ages of 24 to 36 follow a normal distribution.

If 23 women from this population are randomly selected, calculate the probability that their mean systolic blood pressure is greater than ( ) 140.
