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

$= \frac{17}{47}$

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

$1-\frac{17}{47} = \frac{30}{47}$

And that's the required answer .
