Solution

The total songs on Alan's playlist is 169 songs

The probability, P, formula is


P=\frac{Required\text{ outcome}}{Total\text{ outcome}}

There are 15 hip hop songs on Alan's playlist.

The required outcome is 19

The total outcome is 169

To find the probability that the first song played is a hip hop song,

Substitute the outcomes into the formula of probability


\begin{gathered} P=\frac{Requ\imaginaryI red\text{outcome}}{Total\text{outcome}} \\ P=(15)/(169) \end{gathered}

Hence, the answer is 15/169
