Respuesta :
Number of classical songs = 6
Number of rock songs = 7
Number of rap songs = 9
Total number of songs = 6 + 7 + 9 = 22
Number of not rap songs = Number of classical songs + Number of rock songs
Number of not rap songs = 6 + 7 = 13
P(not a rap song) = [tex] \frac{Number of not rap songs}{Total number of songs} [/tex]
P(not a rap song) = [tex] \frac{13}{22} [/tex]
P(not a rap song) = 0.5909
P(not a rap song) = 0.59
The probability of not a rap song selected by Greg's MP3 player Jumble, for the user to listen is 0.59 or 59%.
What is probability?
Probability of an event is the ratio of number of favorable outcome to the total number of outcome of that event.
As the probability of an event can not be more than the number 1. Thus, the probability of failure of an event is equal to the difference of the 1 to the success of the event.
Greg has an MP3 player called the Jumble. The Jumble randomly selects a song for the user to listen to.
Greg's Jumble has,
- 6 classical songs,
- 7 rock songs, and
- 9 rap songs on it.
The total number of song is in his MP3 player,
[tex]n=6+7+9\\n=22[/tex]
Number of songs which is not rap song (6 classical songs, 7 rock songs) is,
[tex]f=6+7\\f=13[/tex]
Thus, the probability is,
[tex]P=\dfrac{13}{20}\\P\approx0.59\\P=59\%[/tex]
Thus, the probability of not a rap song selected by Greg's MP3 player Jumble, for the user to listen is 0.59 or 59%.
