Moderate# Calculating Probability: Average Song Length

APSTAT-XKLNJK

The length of songs played by a certain radio station is approximately normally distributed with a mean of $210\text{ seconds}$ and a standard deviation of $25\text{ seconds}$.

If DJ turns on the radio just in time to catch the beginning of a new song, what is the probability the song will last between $170$ and $225\text{ seconds}$?
