Given data:

Total number of songs = 8

Rock songs = 3

Reggae songs = 2

Country songs = 3

Probability = Number of favorable outcomes / Total number of outcomes

To find:

When song is selected randomly to play first song and then second song from remaining ones ,

Probability when both the songs are from Reggae songs,

\begin{gathered} P\text{ =}\frac{2}{8}\times\frac{1}{7} \\ \text{   = }\frac{2}{56} \end{gathered}P=\frac{1}{28}

Thus , the probability is 1/28.

Volume(v)=4/3 πr^2 = 4/3π 5^3= 4/3π 125 = 166.666666667π = 523.598775599

Rounding to the nearest tenth,

Volume=524cm^2
