Answer:
211*10⁹
Step-by-step explanation:
Total songs = 3country + 6pop + 7 disco + 3hip-hop = 19 songs
Max pop songs = 3
Case 1: no pop songs;
¹³C₁₀*⁶C₀= 286
Case 2: 1 pop song ;
¹³C₉*⁶C₁= 4290
Case 3: 2 pop songs;
¹³C₈*⁶C₂= 19305
Case 4: 3 pop songs;
¹³C₇*⁶C₃= 34320
Total = 58201
so, now if order is also to be considered for making playlists then the number of playlists is =58201*10! = 211*10⁹
