Mekala will listen to close to 60 country songs but probably not exactly 60 country songs
The number of songs on the MP3 player are:
Techno = 4
Country = 2
Jazz = 3
The proportion (p) of songs that are country songs is:
p = Country/Total
So, we have:
[tex]p =\frac{2}{9}[/tex]
When he plays the song 270 times, the expected number of times country songs are played is:
[tex]E(x) =\frac{2}{9} * 270[/tex]
This gives
[tex]E(x) =60[/tex]
Hence, the best prediction is that:
Mekala will listen to close to 60 country songs but probably not exactly 60 country songs
