Question

On her MP3 player, Stephanie has 36 songs shorter than three minutes and 72 songs longer than three minutes. What is the probabilty the next song will be longer than three minutes?

Answer 1

Explanation:

Total songs = 36 + 72 = 108

`required \: probability = (72)/(108) \\ \hspace{100 pt} = (2)/(3) \\`

Hence, probabilty that next song will be longer than three minutes is
`(2)/(3)`
