describe probability values for specified events.
A normal population has a mean of 80.0 as well as a standard deviation of 14.0
1) find out the probability of a value between 75.0 and 90.0
2) find out the probability of a value of 75.0 and less.
3) find out the probability of a value between 55.0 and 70.0
4) find out the probability of a value of 85.0 and more.
