The duration of the class is uniformly distributed with a minimum of 50.0 minutes and a maximum of 52.0 minutes. This means the random variable for class duration 
has density function
![f_X(x)=\begin{cases}\dfrac1{52.0-50.0}=\dfrac12&\text{for }50.0\le x\le52.0\\[1ex]0&\text{otherwise}\end{cases}](https://tex.z-dn.net/?f=f_X%28x%29%3D%5Cbegin%7Bcases%7D%5Cdfrac1%7B52.0-50.0%7D%3D%5Cdfrac12%26%5Ctext%7Bfor%20%7D50.0%5Cle%20x%5Cle52.0%5C%5C%5B1ex%5D0%26%5Ctext%7Botherwise%7D%5Cend%7Bcases%7D)
You're looking for the probability that the class runs less than 51.5 minutes, or
, which is given by the integral
