The compressive strength of cement samples can be modelled by a normal distribution with
a mean of (T + 6000) kilograms per square metre and a standard deviation of (T + 100)
kilograms per square metre.
Find the probability that a sample's strength is between
(T + 5800) kg/m? and (T + 5900) kg/m². Note: T= 96
