Question

Chen has an MP3 player caller the Jumble. The Jumble randomly selects a song for the user to listen to. Chen's Jumble has 4 classical songs, 3 rock songs, and 2 rap songs on it. Chen is going to listen to 360 songs. What is the best prediction for the number of classical song that Chen will listen to?

Answer 1

Chen might lisen 160 classical songs 
you add them all the song 
then you you divide how many song there are by 360 
it should equal 40 so you multipythat by 4
(I hope i got that right)

Answer 2

Number of songs=360

p(classical songs)=4/9

best prediction=360*4/9=160

so they answer is 160.
