Suppose the force acting on a column that helps to support a building is a normally distributed random variable X with mean value 15.0 kips and standard deviation 1.25 kips.
Compute the following probabilities by standardizing and then using Table A.3.
a) P(X ≤ 15)
b) P(X ≤ 17.5)
c) P(X ≥ 10)
d) P(14 ≤ X ≤ 18)
e) P(|X - 15| ≤ 3)

can someone please help? :)
