Answer:
35/79
Step-by-step explanation:
Assuming you can't choose the same song a second time, the probability is 35/79.
If you can choose the same song, the probability is 36/80, which reduces to 9/20.
15+24+3=42
24/42 simplified is 4/7
2940
You are subtracting a negative number. "Minus a negative is plus."
525 - (-2415) = 525 + 2415 = 2940
