Answer 1

The probably of the next song not being a Katy perry song is 30/47

Answer 2

Total number of songs is
`14+16+17= 47`

And out of 47, total number's of katy Pery's songs are 17.

So probability that the next song will be the song of Katy Pery is

`= (17)/(47)`

And therefore probability that the next song is not of Kety's pary's song is

`1-(17)/(47) = (30)/(47)`

And that's the required answer .
